Hi

Crow Valley Camp Ground was smothered with Swainson's Thrushs probably 60 + also some Hermit Thrushes. Also a Plumbius and Warbling Vireo. Bill Fink first spotted 2-3 Cassin’s Kingbirds along Murphy’s Pasture. At the GPGD there were birds every where most of the time—an enjoyable morning. Crow Creek was however was dry as the only negative.

Thanks everyone for the identification help and the great points on detailed field marks. All agreed it was a Warbling Vireo.

Also, sorry for the butterfly pics. I had 3 images of the vireo but grabbed the wrong files.

I am not very good at flycatchers, I’ll admit that right off the top. However, this looks good for a gray flycatcher to me. Almost looks like he has glasses, which fits, pale belly no markings on the abdomen or chest. I don’t see a pink mandible, but it might just be hard at that angle to get.

Subject: [cobirds] Bird Conservancy of the Rockies - Chatfield Banding Station, 5/18/24
It was a beautiful morning - cool, sunny, no wind - and birds were making
lots of noise. Given all that, the numbers today were disappointing - only
15 new birds. (Also caught 10 that had been previously caught this season -
all migrants that are likely to stick around for the summer.) Caught 3 of
the Brown-headed Cowbirds and 1 of the Cedar Waxwings that have been around
for a week or so.

Here's today's breakdown:

Downy Woodpecker 1
House Wren 1
Gray Catbird 2 new, 1 banded 2023
Cedar Waxwing 1
Yellow Warbler 1 new, 1 each banded 2021, 2022, and 2023
Yellow-breasted Chat 1
Chipping Sparrow 1
Brown-headed Cowbird 2 new, 1 banded 2022

We are banding Tuesday through Sunday (closed Mondays) through May 31,
weather permitting. You can register to visit on the weekends through the Denver
Audubon website <https://denveraudubon.org/events/>. (Some times/days are
sold out, so sign up now if you are interested!)

Glad things are picking up!  So cool about that redstart.  I didn't know there was a resident pop of Redstarts there.
I stopped by the Fort Collins station yesterday - looks like its been hopping.

Hello Fellow Birders,
    This Spring's remarkable parade of birds through my little townhouse yard near Holly & Arapahoe in west Centennial continues with the arrival yesterday of a male Black-headed Grosbeak.  The tanagers and orioles appear to have moved on.

Subject: [cobirds] Breeding Bird Survey routes available in Colorado
Colorado Birders,

The North American Breeding Bird Survey
<https://www.pwrc.usgs.gov/bbs/index.cfm> (BBS) is our continent's premier
long term bird monitoring program. There are many active BBS routes in
Colorado, and right now 35 routes are open for a new observer. *Open Routes
are listed below*, and you can view the vacant routes and some details for
each at the BBS's Vacant Routes
<https://www.pwrc.usgs.gov/bbs/RouteMap/Map.cfm> page. Choose the state and
find the route. You can choose to show the route on the map, and view route
details including species recorded on the route in prior years.

Many open routes are in interesting areas of Colorado, and some are near to
the Denver area. If you wish to sign on, your survey materials will be sent
promptly. Routes are surveyed in the window of May 27 to July 7. So the
season is upon us.

If you are an experienced BBS surveyor and would like to add a new route,
great. *If you would be new to the BBS*, conducting these surveys
requires *significant
field ID skills* (especially by ear), and familiarity with the birds that
live in the region. And the BBS is looking for a minimum of a *three year*
commitment to survey the route. You should be able to identify the species
known to be along the route by sound; that is, you, and not Merlin ;-) You
can view the list of species for each route. And be ready for the energetic
commitment and time needed to perform the survey, which might include
distant driving to and from the route on additional days. A scouting day is
usually also needed for a new route.

I'd be happy to talk about what is needed and how to prepare with anyone
who is interested. I've been a BBS surveyor since 1992 and it is the best
part of my birding year. I have multiple routes that I survey in Colorado,
and there are many other surveyors, too, working behind the scenes and
loving it. I think all strong Colorado birders who can make the time
commitment should consider being a BBS volunteer surveyor. You will learn a
lot, too.

Subject: [cobirds] Lewis's Woodpecker, SW Denver
Had to bail on a further afield birding adventure this morning (Thurs., 16
May'24) to take care of some stuff here at the house (Athmar Park, SW
Denver, Denver Co.), so a little bummed. However, Karma does exist and has
come into play as we've had a pretty busy morning so far around here
including a very surprising LEWIS'S WOODPECKER flying over our deck as we
were having breakfast. While this specific bird will likely not be
repeatable, I bring this up to the group as good numbers of Lewis's can
often be seen over broad areas if they happen to move in, so keep your eyes
open.

Subject: [cobirds] Great Horned Finches in west Centennial, Arapahoe County
Hello Fellow Birders,
    We just saw our first fledgling House Finches of the year in our little townhouse yard near Holly & Arapahoe.  The fledglings often have a few unkempt feathers on their heads that are similar to the feather tufts of Great Horned Owls, thus the moniker Great Horned Finch.    In other news, the Bullocks Orioles have moved on but the Western Tanagers are still feeding up for the rest of their journey northward.    And the White-breasted Nuthatches who usurped our nestbox from the Black-capped Chickadees this year are frantically feeding their brood.  I find it interesting that they've been feeding them bits of suet from our homemade suet cake.    Lovely time of year...

Dave Leatherman, long-time member of the Colorado Field Ornithologists, is
our featured speaker in May. Dave’s presentation will describe the wild
foods of Colorado’s birds, discussing their tried and true “go-to” items.
Dave advocates carefully observing a bird for just a few minutes to gather
valuable information on habitat, feeding habits, and other behaviors.
Studying what birds eat is fun and full of surprises. Hope you can join us
to kick off the summer birding season.

PLEASE NOTE: This program will be offered in person only.

Tuesday, May 28, 7:15 – 8:45 pm, at the Unitarian Universalist Church of
Boulder (5001 Pennsylvania Ave).

Subject: [cobirds] Re: Thrush ID help - Adams
Hi Jared,

It looks great for a Gray-cheeked to me (ignoring the unlikely possibility
of a Bicknell's Thrush). Some field marks per Birds of The World
<https://birdsoftheworld.org/bow/species/gycthr/cur/identification> that
particularly stand out on this bird:


- Distinct dark lines at sides of throat coalesce with prominent
brownish-black triangular spots on lower throat and breast


- belly and sides marked with oval-shaped spots (spots wider than long)
distinctly paler than breast spots.


- cold grayish wash on flanks (this color similar to upperparts).


- Contrast between darker triangular anterior spots and pale oval
posterior spots, combined with cold, grayish sides and flanks and minimal
buff wash on breast highly distinctive.

Why it's not a...

Veery: Breast spotting would be less distinct and smudgier. Flanks would
be brighter, and the upper parts should have at least some warm reddish
tones, even on a duller western one.

Hermit Thrush: Should have at least an indistinct eye-ring, a tail and
rump that contrast with the back more. In the absence of a strongly
contrasting tail, I would still expect to see brighter, contrasting
primaries.

Swainson's Thrush: Would have a buffy wash to the face, throat and upper
breast, not to mention the typically bold eyering.

I am mostly familiar with Gray-cheeked from Alaska (and the
northeast/mid-west a long time ago), but I wouldn't hesitate to ID this
bird as one up there.

Subject: [cobirds] Thrush ID help - Adams
Asking for a friend who's not a CO Birds poster: how would you all ID this
thrush, apparently without an eye ring, seen at the Arsenal on May 12. He's
received conflicting suggestions. (It seems like Gray-cheeked Thrushes
moved through the area the past two days?)

Link to Macaulay Library: https://macaulaylibrary.org/asset/618941650
Link to eBird checklist: https://ebird.org/checklist/S174087061

If you prefer, you can email me and I'll pass the messages along.

Thanks!

Subject: [cobirds] LCC Woods, Lamar (Prowers) 13May2024
Present today:
Less birdy in terms of pass-thru migrants than last Saturday but still fun.

Gray-cheeked Thrush (entry/exit trail that runs e-w at north end)

Mourning Warbler (in golden currant thicket 200 yards south of the library feeder area w of trail due west of the swampy area where the northern waterthrushes have been)

American Redstart male (still present w of the trail at the north end among the olives).

Sora (still being heard at north end besides Willow Creek).

Did not find Eastern Towhee reported and photographed recently.

Siberian elms still hosting sparrows, buntings, grosbeaks, catbirds, orioles and warblers because of heavy infestation of European elm flea weevil (larvae in brown, conspicuous leaf mines are the attraction).

Hackberry, flowering honeylocust, mulberry and golden currant also are bird-attractive woody plants currently in se CO.

Total of 47 species this morning at LCC.

Where are the vireos (besides Warbling), red-headed and red-bellied woodpeckers? A very few of these have been reported but not nearly in what I would call “normal” numbers.

Subject: [cobirds] Chico Basin Ranch Banding Station Report/ Bird Conservancy of the Rockies- May 13, 2024
Birds have the urge to move North even when the winds are not helping them
migrate. Northerly winds overnight and during the morning produced a few
migrants at the station.
A few birds were still held over from Saturday and the end of last week.
All Recaptures gained Mass/Weight from their original banding. Two new
species were banded for the season: Hooded Warbler and Veery. The Hooded
Warbler was the male who has been singing near banding table/benches since
Wednesday of last week.
Twelve bird species were captured today including 5 species of warbler.

*24 New Banded Birds*
Yellow Warbler- 3
Hooded Warbler- 1
Ovenbird-1
Myrtle (Yellow-rumped) Warbler- 1
MacGillivray's Warbler- 1
Hammond's Flycatcher- 1
Swainson's Thrush- 14
Veery- 1
Gray Catbird- 1

*5 Recaptures- banded this season*
Ovenbird- 3
Gray Catbird- 2
Gray-headed Junco-1

*3 Returns- banded in previous years here at Chico*
American Robin- banded as an adult in fall 2022-At least 4 years old
Brown Thrasher- 2 banded in fall 2023- 1 adult and 1 hatching year - 1 is
at least 3 years old and one is 2 years old.

Stop by the banding station if you are visiting the Ranch and please share
your sightings.

***Remember Chico Basin is open to a limited number of people each day
during this month. Please go to the Aiken Audubon Website
<http://www.aikenaudubon.com/> to register for a morning to visit. There is
a daily registration fee.
Have a good day,

Subject: [cobirds] Western Tanager - YES!!! - west Centennial, Arapahoe County
Hello Fellow Birders,
    Last Thursday, May 9,  I reported a Western Tanager in my little townhouse yard near Holly St & Arapahoe Rd in west Centennial, based on a small blurry cell phone  photo through a window screen.  I then rescinded that ID when a pair of Bullock's Orioles showed up an hour later and I assumed the male was the same bird I'd glimpsed before and called a tanager.    Just a few minutes ago a male Western Tanager was on the suet, and I'm calling it the same bird I saw last Thursday.  I got a better picture - no doubts this time.  And yes, the orioles are still around, too.

Anyone can see prior years' results from Dinosaur Ridge at

You can use the left sidebar to see either monthly results each year, and
even daily results each and every season.
BTW, you can, on the same website, see results of hawk watches all over the
country as well as Central and South America, not just in Spring but also
in Fall.
In spring for example you can see the wave of raptors starting from South

Subject: [cobirds] Bird Conservancy of the Rockies - Chatfield Banding Station, 5/11/24
The big wave of migrants either passed us by or we missed it due to being
rained out yesterday. We did pick up our first Swainson's Thrushes today,
about 10 days later than our average first arrival for the species. Banded
17 new birds, plus caught 3 returns from prior years:

Dusky Flycatcher 1
House Wren 3
Swainson's Thrush 3 FOS
Gray Catbird 3 new, 2 returns (1 banded in 2021, 1 in 2023)
Yellow Warbler 1 new, 1 banded in 2021 (and recaught in 2022 and 2023)
Wilson's Warbler 1
Song Sparrow 1
Lincoln's Sparrow 3
Red-winged Blackbird 1

We are banding Tuesday through Sunday (closed Mondays) through May 31,
weather permitting. You can register to visit on the weekends through the Denver
Audubon website <https://denveraudubon.org/events/>. (Some times/days are
sold out, so sign up now if you are interested!)

near banding station. The Hooded Warbler was singing and still bopping
around the banding station area along the north side of grove.

> Why does Mother’s Day occur at the peak of Spring Migration? This must have been the idea of some deranged member of Congress. (Excuse the redundancy). Sure, many if not most of us birders love our moms, and are just fine with honoring them, but why not in February, when one is less likely to miss a warbler? Birders have lamented the inconvenient calendric placement of Mom’s Day ever since John James Audubon dumped Mrs. Audubon one May 13th to go afield. Here is a proposal to celebrate Mother’s Day in style and still have a shot at seeing great birds the very same day.
>
> I propose a modest solution - take Mom to Phillips County for a Mother's Day excursion she will forever cherish! Your older brother, Mr. Fancy Pants and your bossy “Big Sis” might have been taking Mom to the Bahamas, Paris or Hawaii, but I'll bet they never were thoughtful enough to guide Mother to such a gem-like destination. Be it Haxtun or Holyoke, the sewage ponds of Phillips County beckon!
>
> Make the best of it, take Mom on a grand tour of Phillips County, the jewel of the north-eastern plains, a thrill for her AND a birding opportunity for you. I would consider this gesture generous, not selfish, because let's face it, every Mother's Day until now has not been warbler-centric, but has been all about her!
>
> Pack up the “bird-mobile,” dust off your spare pair of bins, head northeast from almost anywhere in our state and after a quick four to twelve hour drive - presto, you're there. Whether over the decades Mom has become a seasoned birder or remains a novice, Phillips County will reveal its avian treasures to the sharp-eyed. As a warm-up to spotting the avifauna, why not start with a meal in the cuisine capital, downtown Holyoke? There snuggled together on a single block are truly savory international houses of fine dining - not only gourmet standard American style, but Chinese, Mexican, Sub, Donut Shop and Convenience Store flavors. Then how about shopping for a Mother’s Day card and some gifts on cosmopolitan Interocean Avenue? The Deaver Hardware Store has a sidewalk display of colorful hanging floral baskets. Or let Mom go inside and have her pick of Mother's Day gifts from the enticing "75% off” rack. She'll be surprised at the selection - items she won’t find at Nordstrom’s, where your sister takes her. And at the Haxtun Super, there are special Mom's Day sales on Skoal and Copenhagen for her everyday needs, Carhartt coveralls in denim, canvas and camo and for her garden, 25 lbs of steer manure for $9.99 (bagged) or for as low as $1.99, "bag it yourself."
>
> And now let’s go birding! I’d guess that Mom's Phillips County bird list is pretty low. Be sure to have a brand-new notebook, a county checklist and a writing implement. She can't miss Eurasian Collared Doves, Horned Larks are ubiquitous and Swainson's Hawks can be seen without much trouble. Tick ‘em off! If she is squeamish about odiferous emanations from the famed sewage ponds, assure her that the repulsive fragrances are just not going to be a problem, due to their location across the road from the Farfal Brothers' Feed Lot, whose fumes will overpower anything the ponds can throw up at you. And it's not just those little lakes that offer magic. Good migrants can be found along County Road 14 and in the famed migrant traps of Paoli and Amherst. (Check for feeders; some were there in 1992).
>
> Next it’s you and Mom strolling arm and arm through the kochia weeds to reach Frenchman’s Creek Wildlife Area. What? It’s bone dry? No ducks! No shorebirds! Oh, well, that’s birding. There’s always a chance to troll the desolate grid of gravel roads northwest of Holyoke for Loggerhead Shrike and kingbirds. That may induce a short nap, which folks Mom’s age will relish.
> But the excitement must come to an end. As evening falls, and you wend your way home, be patient with your dear Mother. She will want to relive the details of how intense were her labor pains, how numerous were the diapers she changed, and how her hopes and aspirations for your development as a person of character (and wage-earner) were repeatedly dashed, through no fault of her own. But let it all go in one ear and out someplace else while you mentally play back the buoyant songs of the Western Meadowlark, remember the wide-open spaces, feel the high winds and remember the rare ducks floating along - on the sewage ponds of Phillips County.

This is a ten year old email message from Joe Roller I found I had saved and it is just in time for Mother's day.  When I first read this, I thought who could make this up?  I will send this to my daughters so maybe some year, this trip could become a reality for me to go on with them!Best,Kathy Miller


----- Forwarded Message ----- From: "Joe Roller" <jroller9...> To: "Colorado Birds" <cobirds...> Cc: Sent: Sat, May 10, 2014 at 6:14 PM Subject: [cobirds] The Sewage Ponds of Phillips County and Other Mother's Day Travel Ideas.
(Posted despite popular demand from a 2009 birding essay).







Why does Mother’s Day occur at the peak of Spring Migration? This must have been the idea of some deranged member of Congress. (Excuse the redundancy). Sure, many if not most of us birders love our moms, and are just fine with honoring them, but why not in February, when one is less likely to miss a warbler? Birders have lamented the inconvenient calendric placement of Mom’s Day ever since John James Audubon dumped Mrs. Audubon one May 13th to go afield. Here is a proposal to celebrate Mother’s Day in style and still have a shot at seeing great birds the very same day.




I propose a modest solution - take Mom to Phillips County for a Mother's Day excursion she will forever cherish!  Your  older brother, Mr. Fancy Pants and your bossy “Big Sis” might have been taking Mom to the Bahamas, Paris or Hawaii, but I'll bet they never were thoughtful enough to guide Mother to such a gem-like destination. Be it Haxtun or Holyoke, the sewage ponds of Phillips County beckon!




Make the best of it, take Mom on a grand tour of Phillips County, the jewel of the north-eastern plains, a thrill for her AND a birding opportunity for you. I would consider this gesture generous, not selfish, because let's face it, every Mother's Day until now has not been warbler-centric, but has been all about her!

 

Pack up the “bird-mobile,” dust off your spare pair of bins, head northeast from almost anywhere in our state and after a quick four to twelve hour drive - presto, you're there. Whether over the decades Mom has become a seasoned birder or remains a novice, Phillips County will reveal its avian treasures to the sharp-eyed.  As a warm-up to spotting the avifauna, why not start with a meal in the cuisine capital, downtown Holyoke? There snuggled together on a single block are truly savory international houses of fine dining - not only gourmet standard American style, but Chinese, Mexican, Sub, Donut Shop and Convenience Store flavors. Then how about shopping for a Mother’s Day card and some gifts on cosmopolitan Interocean Avenue? The Deaver Hardware Store has a sidewalk display of colorful hanging floral baskets. Or let Mom go inside and have her pick of Mother's Day gifts from the enticing "75% off” rack. She'll be surprised at the selection - items she won’t find at Nordstrom’s, where your sister takes her. And at the Haxtun Super, there are special Mom's Day sales on Skoal and Copenhagen for her everyday needs, Carhartt coveralls in denim, canvas and camo and for her garden, 25 lbs of steer manure for $9.99 (bagged) or for as low as $1.99, "bag it yourself."

 

And now let’s go birding! I’d guess that Mom's Phillips County bird list is pretty low. Be sure to have a brand-new notebook, a county checklist and a writing implement. She can't miss Eurasian Collared Doves, Horned Larks are ubiquitous and Swainson's Hawks can be seen without much trouble. Tick ‘em off! If she is squeamish about odiferous emanations from the famed sewage ponds, assure her that the repulsive fragrances are just not going to be a problem, due to their location across the road from the Farfal Brothers' Feed Lot, whose fumes will overpower anything the ponds can throw up at you.  And it's not just those little lakes that offer magic. Good migrants can be found along County Road 14 and in the famed migrant traps of Paoli and Amherst.  (Check for feeders; some were there in 1992).




Next it’s you and Mom strolling arm and arm through the kochia weeds to reach Frenchman’s Creek Wildlife Area. What? It’s bone dry? No ducks! No shorebirds! Oh, well, that’s birding. There’s always a chance to troll the desolate grid of gravel roads northwest of Holyoke for Loggerhead Shrike and kingbirds. That may induce a short nap, which folks Mom’s age will relish.                   

But the excitement must come to an end. As evening falls, and you wend your way home, be patient with your dear Mother. She will want to relive the details of how intense were her labor pains, how numerous were the diapers she changed, and how her hopes and aspirations for your development as a person of character (and wage-earner) were repeatedly dashed, through no fault of her own. But let it all go in one ear and out someplace else while you mentally play back the buoyant songs of the Western Meadowlark, remember the wide-open spaces, feel the high winds and remember the rare ducks floating along - on the sewage ponds of Phillips County.

 

 

Joe Roller, 

Denver

Observation start time: 09:00:00
Observation end time: 17:00:00
Total observation time: 8 hours

Official Counter: Dustin Kohler

Observers: Mike Fernandez, Zach Hope

Visitors:
We had 23 Visitors to the ridge today.


Weather:
We had a very cloudy day with light wind from the east all day. There was a
fog that turned into a natural fog/haze towards the end of the day.

Raptor Observations:
All of our migrants were low and almost all were above or slightly east of
us.

We had the continued conflict between a Golden Eagle trying to exist, and a
bunch of Red-tailed Hawks not wanting it to exist near their nests. Later a
Golden Eagle was chased by another Golden Eagle.

We also had a local Peregrine Falcon, and a few local Turkey Vultures.

We had a Cooper's Hawk fly by about midday carrying a bird probably back to
its nest. Later a Cooper's Hawk dove into a bush after a Spotted Towhee,
but missed and flew away pouting.

Non-raptor Observations:
We had a Blackpoll Warbler at the ridge today!! I didn't know that they
made it to Colorado. We also had a House Wren which means that I have now
seen every wren species that makes it to Colorado except Marsh Wren from
the ridge.

We also had a Brown-headed Cowbird, Blue-gray Gnatcatchers, Rock Wren,
Spotted Towhees, Western Meadowlark, Chipping Sparrow, White-breasted
Nuthatch, Broad-tailed Hummingbird, Double-crested Cormorant, Mourning
Dove, White-throated Swift, Tree Swallow, Violet-Green Swallow, and
probably others that I forgot to write down.

Predictions:
This was our last day of the season. Thank you to all of our Volunteers for
helping us so much this year, and a big thank you to the Hawk Watch
Coordinators, Project Lead, and everyone else who helped me get this
amazing experience.

This is not a goodbye Dinosaur Ridge, but a see you later.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

I stayed after the banding was done and found this blackpoll warbler. It took me a while to figure out what I was seeing and I’m glad I got a decent picture.
I hadn’t been doing any eBird, but I’ll put it in when I get a chance when I get home. It takes me a while to figure out how to get the right location in, etc.

From: Chicobander <jshieldcastle...>
Subject: [cobirds] Chico Basin Ranch Banding Report/ Bird Conservancy of the Rockies- May 10, 2024
A cloudy day and I wasn't sure what to expect today at the banding station.
A few Swainson's Thrushes and not as many small birds were banded. Today's
spotlight was a Gray-cheeked Thrush that was just confirmed by Colin
Woolley, band manager for Bird Conservancy of the Rockies with the photos I
submitted to him. He said a Gray-cheeked Thrush has not been caught at
Chico Basin Ranch banding station since 2014.

Other highlights were first of the season Western Flycatcher (Cordilleran),
Ash-throated Flycatcher, Northern Waterthrush, and Bullock's Orioles (these
Orioles have been around for several days as has been the Ash-throated
Flycatcher).

There was/is a male Hooded Warbler that toward the end of the morning was
feeding on the ground or knee high near the benches at banding station for
a couple hours until we closed the station (could still be there). It is
not banded so not the male we had hang out at the station last spring for
many weeks.

*110 New Banded Birds*
Audubon's (Yellow-rumped) Warbler- 2
Myrtle (Yellow-rumped) Warbler- 1
Yellow Warbler- 8
Wilson's Warbler- 2
Orange-crowned Warbler- 3
American Redstart- 1
Common Yellowthroat- 1
Ovenbird-2
Northern Waterthrush- 1
House Wren- 2
Least Flycatcher- 1
Hammond's Flycatcher- 1
Western (Cordilleran) Flycatcher- 1
Ash-throated Flycatcher- 1
Western Tanager-1
Bullock's Oriole- 2
Swainson's Thrush- 68
Hermit Thrush- 3
Gray-cheeked Thrush- 1
Lincoln's Sparrow- 1
Gray Catbird- 7

*4 Recaptures and 1 Returning bird from previous year*
Ovenbird- 1
Swainson's Thrush- 2
Gray Catbird- 1
Brown Thrasher returning again to the station-first banded in fall 2022 as
a Hatching year bird.

No matter where you go there is bird migration going on. Enjoy the season!
The banding will be open tomorrow from sunrise until @11 am and will be
closed on Sunday. Stop by the banding station if you are visiting and share
your bird sightings.

***Remember Chico Basin is open to a limited number of people each day
during this month. Please go to the Aiken Audubon Website
<http://www.aikenaudubon.com/> to register for a morning to visit. There is
a daily registration fee.
Have a good day,

Hello Birders,
      At about 2:00 this afternoon a turkey walked across my front yard at Yale and South Niagara St.  It continued to walk down the south sidewalk which is along Yale.  It stopped now and then to forage on whatever it found in the grassy parking strip.  Don't know where it will end up, not in the busy street, I hope.         Liz Willcockson

There is truly an issue as the rehabber I volunteer for in Colo. Sprgs is getting calls on Poorwills. She has taken in 5 so far, one didn't survive, and one has feather damage, the one brought today is cold and thin, and one "baby owl" (Poorwill) found 3 days ago in a warehouse not yet captured/removed to the outdoors.
Perhaps our cold temps lately,  no/low miller moths in the air are affecting their migration? Certainly tragic, be on the lookout.

Observation start time: 08:30:00
Observation end time: 17:00:00
Total observation time: 8.5 hours

Official Counter: Dustin Kohler

Observers: Bill Young, Dave Erickson, Emma Riley, Mike Serruto,
Steve Ryder

Visitors:
We had 13 visitors to the ridge today including 2 determined ladies that
had come up on 2 separate occasions this week, but they had previously come
up when weather or our time parameters prevented them from meeting us.

This was Emma's last day for the season. Thank you for all the lessons and
the memories.


Weather:
We had 100% cloud cover all day, but the sun did somehow shine through for
the last couple hours. It snowed/rained for the first few hours. The wind
was from the east all day.

There was a winter weather advisory after 3, but that was our warmest time
of the day.

Raptor Observations:
Our migrants were relatively low and mostly on the east or above us.

One Swainson's Hawk of unknown age was our furthest away bird, and the
other Swainson's was probably in juvenile plumage two months ago.

The Peregrine Falcon was attacked by another Peregrine as it flew north.
There was a high-speed chase that went on for miles before the second bird
circled back over us and southward.

In local news we had at least one Red-tailed Hawk attacking a Golden eagle
most of the morning. Later we had 3 Golden Eagles and 2 Red-tailed hawks in
the air at the same time, but only one of each were near the other.

We also had a juvenile Bald Eagle and a Dark Morph Red-tailed Hawk that
didn't migrate.

Non-raptor Observations:
We had 3 Western Tanagers to the ridge today, a lifer for this kid from
Missouri, it seems like they have just got back into town.

We had a flock of 11 American White Pelicans, and a Common Raven flying
with a rodent in its beak.

We saw Elk, Mule Deer, and a Red Fox on our ridge today as well, always fun
to see those guys.

Predictions:
It looks to be rainy for the first couple of hours before being mostly
cloudy. The wind should be moderate and out of the East or East of
Northeast all day. Not the best day for migrants, but as it will be our
last day of the season I hope to get a few good migrants.
========================================================================
Report submitted by Official Counter (<j.f.peters58...>)
Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Subject: [cobirds] thanks to DFO and Dinosaur Ridge Hawk Watch for a great season
I wanted to post a big thank you to DFO and the monitors at Dinosaur Ridge
for a great season! I look forward to the counts every day, and am always
thrilled when I see the first Turkey Vultures returning. To me, that's the
start of Spring. This season, I've been wondering which bird species would
get the greatest number of migrants: Red-tailed Hawks, American Kestrels,
or Turkey vultures? I don't know the numbers from past years, but I was
surprised that the AMKE (490) beat out the RTHA (460) as of May 8. Thanks
for the dedication of the monitors and the great reports. Welcome all the
migrants!

Subject: [cobirds] Reminder - BCAS Field Trip: “Mindful Birding” at Goshawk Ridge, May 16
Join Peter Ruprecht for this unique birding field trip whose theme,
"mindful birding," means that we will spend quiet time at each of several
stopping points to focus deeply on any birds that we are able to see and
hear. Rather than finding and identifying as many species as possible,
we’ll focus on appreciating the ones we happen across. Goshawk Ridge
provides exceptional scenery and a variety of high-quality habitats. Plan
on walking about two miles on gravel road.

Registration required. Limited to only 8 participants. RSVP to reserve your
spot.

Thursday, May 16, 7 am – 10 am

Subject: [cobirds] Re: I hesitate to report this sighting from Boulder County
No reason to hesitate. As a wildlife rehabilitator in northern Colorado, I
have taken several calls about Common nighthawks/poorwills over the last
couple weeks from citizens finding "small baby owls" on the ground first
thing in the morning. While there are many young Great horned owls out
there, several calls with associated pictures have confirmed that they were
indeed our insectivorous friends in torpor making their way back for the
summer.

Official Counter: Emma Riley

Observers: Chip Dawes, Clay Gibson, Karen Fernandez, Marirosa Donisi,
Mike Fernandez

Visitors:
Thank you to everyone who came out today and for all of your help this
season. We had a nice day today and Chip and Marirosa were rewarded with
the Goshawk. We had a raptor researcher, John, spend some time with us
today which was a treat. We also had a visit from Chris late in the day who
was able to get photos of the Goshawk. In total we saw 13 visitors on this
windy day.


Weather:
We started late today to avoid the worst of the winds, and while I think we
accomplished that we didn’t get much relief from them today with gusts up
to 27 mph (measured hourly, could have been higher at times). Luckily the
sun was out today so it was not nearly as cold as it was yesterday. The
winds died down for a bit in the afternoon but picked back up at the end of
the day.

Raptor Observations:
Migration is coming to an end with a total of 10 migrants today. One of my
favorite parts of these high wind days is that birds hug the ridge, giving
us great looks. At one point we had two male AK moving at the same time,
one on either side of the ridge.

We had a fun day with local raptors today. The local RT were seen kiting
for most of the day as they tend to in these winds. We had both BE and GE,
and twice today we saw a GE being mobbed by up to three RT at once. We also
saw a local CH.

The star of the show today was a bird I’ve been wanting for three years
now. It always seems that others get incredible looks at adult AG at this
site, and if you know me you know I’ve been wanting a goshawk to “stare
at me in the soul” and today was the day. A few minutes after 1700 we had
the most picture perfect adult AG fly directly along the ridge, cutting
over towards Green Mountain just meters in front of us. We were lucky
enough to have a photographer there with us that got some unbelievable
shots of this bird. This is my season highlight without a doubt and I am so
glad I was able to share it with a few volunteers.

Non-raptor Observations:
Passerine activity picked back up today with the usual suspects being seen.
We had eerily low CORA activity, though, with only two seen all day. We got
great looks at the BGGN that has been screaming along the ridge the last
week or so.

Predictions:
Precipitation is predicted for tomorrow and I’m crossing my fingers it
will stay light and allow us to count for a full day, my last day of the
season.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Subject: [cobirds] "poor will" flight call at night
1.  There is a flight call that I hear only at night from a bird flying
over the hogback. It sounds exactly like "poor will". The first syllable
is a bit downward-pitched and the second syllable is quicker and
slightly upward-pitched. It is not as fast as whippoorwill calls I've
heard online, and is missing the first syllable of the typical
whippoorwill calls. It is clearly in flight as the source of the call
moves quickly. Any ideas what this bird might be?

2.  I was watching a crow on my back fence the other morning and it was
cawing lustily, when suddenly it put its head down and to the left and
said "hello, hello, hello". It cawed again, head up, then ducked its
head and repeated the "hello, hello, hello" before flying off. I've seen
crows as pets mimicking speech, but this is the first crow I've seen in
the wild making sounds like human speech. Anyone else seen this before?

3.  Third, and finally, while I love having White-crowned Sparrows in
the back yard, they consistently, and *much* more frequently than other
birds, poop in my bird baths. While I've not actually seen them do this,
my bird baths remain much cleaner when they're not around. Anyone else
see this behavior?

Thanks in advance for your responses.

Subject: Re: [cobirds] Shrike Strikes
CObirders,
My fun shrike story starts with leading a field trip to South Padre Island
at the Rio Grande Valley Birding Festival about a decade ago. At the SPI
Convention Center, we found a Swainson's Warbler, rare most anytime but
definitely in Nov, and called back to festival HQ in Harlingen to let them
know so they could spread the word.
I radioed the other half of our group, led by Louise Zemaitis and Michael
O'Brien, that we had a Swainson's Warbler and they quickly came over with
their group. While we were watching the warbler, a Loggerhead Shrike
swooped in, grabbed the Warbler and quickly decapitated it. We had to call
back to festival HQ with a reluctant, "Never mind."

Cheers,
Chip Clouse

Subject: [cobirds] Sharing my new Audubon essay on Whip-poor-wills
Hi all --

A few days ago, Audubon published an essay
<https://www.audubon.org/news/whip-poor-wills-chant-wanes-our-cultural-loss-grows>,
"As the Whip-poor-will's Chant Wanes, Our Cultural Loss Grows," I've
written on Eastern Whip-poor-wills, species decline, and human cultural
change. Here's their description from social,

"Portending everything from new life, to death, to love, to even haircuts,
Eastern Whip-poor-wills and their nighttime calls have been cultural
touchstones in North America for centuries. But as Eastern Whip-poor-will
populations wane, Jared Del Rosso fears we may be losing our deep
connection with the species. Read his advice on reconnecting with these
covert birds and fueling more meaningful connections with the species
around us."

I know Whip-poor-wills aren't CO birds, but there are two Colorado
connections here. The first is that it's my own experience with CO's Common
Nighthawks and Common Poorwills that brought me to this work; I touch on
the nighthawks in this essay (and I've posted about them here--probably too
often!). The other is that my writing and thinking on this often draws on
the work of the lepidopterist Robert Michael Pyle, who grew up along the
High Line Canal in Aurora. Pyle's book *The Thunder Tree* details his
youthful discoveries and losses along the Canal, and these figure in my
essay. And I guess I'd add that I've heard many of the same things about
Common Nighthawks in Colorado as I'm hearing about Whip-poor-wills back
east: they once were more common, a sort of annual marker of our springs
and summers; now, they're far more difficult to encounter.

Subject: Re: [cobirds] Re: Shrike Strikes
A few years ago, I spent some time watching a Northern Shrike at Willow
Spring Open Space in Centennial. (I posted a bit about it here, and the
links that follow go back to some old posts.) I observed it hunting insect
larvae <https://groups.google.com/g/cobirds/c/L3aucxokPpU/m/TSjCwlLGAQAJ>;
Dave Leatherman suggested it was likely an Army Cutworm Caterpillar. I also
saw it fetch a small rodent
<https://groups.google.com/g/cobirds/c/53HDvJ12Xyg/m/y-xsooNaCAAJ> - a
mouse or vole. Often, the shrike would disappear with the food into nearby
but inaccessible thickets (at least inaccessible to me), so I could never
tell if the shrike was eating or caching food. I never saw the shrike hunt
birds, though American Tree Sparrows that year were numerous.

The shrike was incredibly patient (at least more patient than me),
remaining perched for painfully long times (at least for me). Often, it
would preen as it also seemed to keep an eye on the sky (for hawks) and the
ground (for prey).

Yes others noted the stashing of the prey. This bird could not lift the
house sparrow. But it tugged like crazy against a chicken wire fence
protecting a shrub. Finally, it went around it and hid the prey in a
greasewood shrub. Nice to know others have witnessed this phenomenon.

Subject: Re: [cobirds] Shrike Strikes
Interesting how many instances of shrike predation everyone has seen.  It's sort of like the yard checklist; when we start looking, all sorts of stuff comes out of the woodwork.  Several winters ago I had a northern shrike that returned to the yard three years in a row.  On one of those occasions, I also had a (for me) rare flock of rosy-finches.  The shrike killed a rosy-finch and stashed the body in a lilac.  I would rather have seen a different prey item, but nature is what nature is: red in tooth and claw.

Observation start time: 09:00:00

Total observation time: 2.75 hours

Official Counter: Emma Riley

Observers: Ajit Antony, Liza Antony

Visitors:
Thank you to Ajit and Liza Antony for their help in the cold today, as well
as all of their help this season and in seasons past. As this season comes
to an end we are saddened to be saying our goodbyes and want to take this
opportunity to show our appreciation. We had 2 brave visitors at the site
today.


Weather:
Winds were strong today from the WSW with slurries moving in in the late
morning. Due to this we ended the count early today.

Raptor Observations:
We had two migrants today with one being a BW, continuing another good BW
season for our site. Both migrants came overhead at a higher flight height
than expected with the winds.

We saw non-migrating RT, CH, and TV today. Raptors activity was all around
low today.

Non-raptor Observations:
BBMA, CORA, WEME, BTHU, and BGGN were the only passerines seen or heard
today. Passerine activity was also eerily low today.

Predictions:
Winds are predicted to continue tomorrow at hopefully lower speeds and
without the cold precipitation. This spring continues to remind us that we
cannot predict the next day, let alone the next hour.
========================================================================
Report submitted by Official Counter (<j.f.peters58...>)
Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Subject: [cobirds] Chico Basin Ranch Banding Station Report/Bird Conservancy of the Rockies- May 7, 2024
Today was a calmer wind day than yesterday. Winds were too strong for
operating the banding station yesterday. Total of seven species captured
today including one recapture. The Recaptured Orange-crowned Warbler gained
weight from its first capture on May 1st.
A male Rose-breasted Grosbeak and a pair of Black-headed Grosbeaks were
observed nearby the banding station in the cottonwoods. The Ash-thorated
Flycatcher was putting on a show by perching close to the ground within 10
feet of birders.

*6 New Banded Birds*
Hammond's Flycatcher- 1
Hermit Thrush- 1
Yellow-breasted Chat- 1
Gambel's White-crowned Sparrow- 1
Spotted Towhee- 1
Brown Thrasher- 1

*1 recapture*
Orange-crowned Warbler

***Remember Chico Basin is open to a limited number of people each day
during this month. Please go to the Aiken Audubon Website
<http://www.aikenaudubon.com/> to register for a morning to visit. There is
a daily registration fee. FYI- as far as I can tell, the sign up has not
reached full capacity as there has been little birder activity on the Ranch
this past week.

The banding station will be operating tomorrow through Saturday this week
from sunrise to @ 11 AM. Please stop by and share what you are seeing on
the ranch.
Enjoy the day!

Sunday was a lot like Saturday - cloudy and cool most of the morning, with
a similar mix of species. Banded 18 new birds, caught 3 returns (banded
here in prior years), and another 7 recaps (birds caught previously this
season). Here's the breakdown of the 21 new this season birds:

Black-capped Chickadee 1 banded 2023
House Wren 5 new, 1 banded 2022
Orange-crowned Warbler 1
Yellow Warbler 1 new, 1 banded 2023
Common Yellowthroat 2
Spotted Towhee 2
Song Sparrow 2
Lincoln's Sparrow 1
White-crowned Sparrow, Gambel's 1
White-crowned Sparrow, Mountain 1
Red-winged Blackbird 2

Happy that today is our day off - this wind would prevent us from opening!
Back out tomorrow.

We are banding Tuesday through Sunday (closed Mondays) through May 31,
weather permitting. You can register to visit on the weekends through the Denver
Audubon website <https://denveraudubon.org/events/>. (Some times/days are
sold out, so sign up now if you are interested!)

Official Counter: Dustin Kohler

Observers: Audrey Anderson, Emma Riley, Jordan Gerue, June Peters ,
Kenny Arroyo, Mike Lupini, Natalie Uschner-Arroyo,
Nick Spade, Zach Haag

Visitors:
We had 55 visitors to the ridge today. We had Jordan Gerue and Nick Spade
visit the site and they stayed helping us spot for a while. We had a
visitor named Michelle who inquired about bringing school groups up to the
ridge next year.

We had our end-of-the-year party where Janet Peters, Mike Lupini, and June
Peters helped provide Empanadas for this year's Hawk Watchers.


Weather:
Moderate wind throughout the day that shifted and got stronger towards the
end of the day. Heavy cloud cover for the first half, and partly cloudy for
the second half. A haze most of the day that affected distant visibility.

Raptor Observations:
Migrates were lower than the last few days, but got higher as the day went
on. Most of the migrants were above us or to the west.

In the first hour, a Sharp-shinned Hawk buzzed by us, and I only noticed it
when the bird song stopped on that side of the ridge.

We had a Broadwing Hawk and a Red-tailed Hawk migrate that had immature
wings, but adult tails. Another Adult Red-tailed was missing a couple of
primaries, and a different Red-tail was a dark morph immature.

We had an immature Red-tail that migrated eating a mouse that it had just
stopped to catch, and our Osprey had a fish.

In local news, we had the male kestrel hunting around us a few times today.
Towards the end of the day, we had a Red-tailed Hawk carrying a snake.

Non-raptor Observations:
Today at the ridge we had a Blue Jay, a few Western Kingbirds, a Chipping
Sparrow, a couple of Rock Wrens, and some others that I didn't write down.


We had a few Mule deer on our ridge on the east side.

Predictions:
Tomorrow has severe winds all day. Canceled count likely.

The banding station in Fort Collins is operating at full speed as migration
revs up over the foothills. Starting the week on Wednesday after a
rainstorm closure over the weekend, the station operated 10 mist nets in
the forest area of Pineridge Natural Area. The majority of captures were
Myrtle and Audubon's Yellow-rumped Warblers, including some interesting
hybrids, along with Orange-crowned Warblers, Lincoln Sparrows, and
Red-Winged Blackbirds. We had many visitors including Fort Collins Audubon,
two school groups, and families who stopped by to watch the action. Each
week I will provide the season totals for new and recaptured birds,
indicating what species is new from the week before with a *.

Visitors:
We had 71 visitors to the ridge today. One person was jogging with hiking
sticks. I have seen a lot of people with walking sticks and a lot of
runners, but this was my first time seeing both. There was another visitor
who sounded like the singer Reba.

There was also a visitor to the ridge today who works in the HR department
for Jefferson County Open Space, I believe. He was also from the St. Louis,
Missouri area (like me), and was wearing a Kshe95 (radio station) T-shirt.


Weather:
Today started cold and cloudy and ended warm and relatively cloudless. The
wind was very gusty and the gust were pretty far apart most of the day. The
wind varied from Northeast to Southeast, but was mostly east all day.

A distant haze affected our visibility all day.

Raptor Observations:
Today started slow and continued to do so throughout the day. The few
migrants we had today were relatively low compared to the last couple of
days, but they were still extremely high.

Two Golden Eagles soared up and went North one a few hundred feet behind
the other one and went way further north than the closest nest that I know
of.

A Cooper's Hawk was chased North juvenile Red-tail, and a different
Cooper's Hawk was also attacked by a red-tail that I couldn't tell what age
it was.

We also had a dark morph immature Swainson's hawk and a non-Harlan's dark
morph Red-tail.

We had a Kettle of 11 Turkey Vultures, but only 8 migrated to the
Northwest.

In local news we had our usual Red-tails, and one of them was carrying
either food or nesting material. I think I saw a squirrel's tail, but it
could have been plant material.

We also had a Red-tailed hawk chasing a Golden Eagle. There was a Cooper's
hawk that went south.

The male American Kestrel was back again today a couple times, hunting or
just hanging out near us.

Non-raptor Observations:
There was a subdued start today in all activity. We had a lot of blue-gray
gnatcatchers screaming all day long. They even outscreamed the Spotted
Towhees and Western Meadowlarks. We saw a Western Kingbird, Common Raven,
Double Crested Cormorant, American White Pelicans, White-throated Swift,
and many swallows.

Predictions:
Tomorrow should be a mostly cloudy day with warm temperatures and a strong
wind from the south. I am hoping for a good migrant day.

Hey COBirders,

I had a pretty good day banding at Clear Spring Ranch, Saturday. While it was cloudy, cold, and breezy until 10:00, some birds were active early. 18 birds banded, and three recaps from this week, mostly before 8:30. Including:

2 Blue-gray Gnatcatchers (4 this week)
8 Yellow-rumped Warblers in one net, 5 Audubon’s and 3 Myrtles. (I only usually catch 2-3 per year because they stay so high, so this was a surprise.)
5 Orange-crowned Warblers, 3 orestera ssp, and 2 celata ssp
Virginia’s Warbler and Com Yellowthroat recaps from yesterday
Lincoln’s (new) and Song (recap) Sparrows, Spotted Towhee (F).

Plus saw the first swallow of the season, a N Rough-winged, and the first Black-headed Grosbeak (M).

Bird Cast predicts a High migration rate tonight, so we’ll see if that translates to some new birds.

Have a birdy weekend,
Steve Brown

Observers: Bill Young, Chris Gearhart, Sammy Korengut ,
Shannon Campbell, Steve Ryder

Visitors:
We had 37 visitors to the ridge today including Piper Vance who came up
with her family and said "There's one!" She spotted one of our Cooper's
Hawks that migrated today.


Weather:
Today was an overall sunny day that got more overcast as the day went on.
Warm temperatures and a steady, moderately strong wind were good conditions
for our migrants. The wind then began shifting from the west and eventually
the north and increased its gusts to over 25 mph consistently which caused
us to cut the count short.

There was a consistent haze that made distant migrants even harder to find
and follow.

Raptor Observations:
The migrants were in all directions but were mostly straight above us and
very high. The migrants started low for the first hour but rose higher and
higher as the day and the wind increased.

Our first three Broadwings left one after the other in a line, but we
didn't see the kettle that they left from. A later Broadwing we hear
vocalizing at another one above it.

We had a Cooper's Hawk aggressively defend itself from a local Red-tail
that moved up to escort them north. Another Cooper's Hawk that migrated was
missing 2 secondaries on their right wing. A different Cooper's was
attacked by a migrating kestrel as it left town.

As the wind increased our migrants got even higher up and were traveling a
lot faster until the wind switched to the west.

We had a kettle of 6 Turkey Vultures that went north for a few miles before
turning around and going back south. Much later we also had a Swainson's
Hawk go to the South.

We had an immature Peregrine Falcon fly south at eye level. One of our
other local Falcons was a Merlin that attacked a Red-tail on its way
south.

We had a Golden Eagle hunting to the west, and a Cooper's Hawk had a talon
full of grass, and a mouse, as it flew off towards where its nest is
located.

During the heavier winds, I heard a squeaking sound. I looked over and saw
a mouse screaming in terror as a male Kestrel had caught it and was flying
south with it.

Non-raptor Observations:
We had a lot of Broad-tailed Hummingbirds zip past us in the wind, they
were more heard than seen. There were also plenty of Swallows and
White-throated Swifts playing in the wind as well. However, once the wind
got above 20 mph the Swallows and Swifts must have gone to ground because
we were not seeing them.

We saw another Western Kingbird this morning and some Common Grackles.
Blue-gray Gnatcatchers also continue to remind us that they are back in
town, challenging the Spotted Towhees and the Woodhouse's Scrub-Jay for the
loudest birds at the ridge.

Predictions:
Tomorrow looks to be a moderately warm day with a steady eastern wind. The
clouds look to cover more and more of the sky as the day goes on for the
third day in a row. There is some rain in the evening that might give our
migrants some incentive to leave a little earlier in the day.

Subject: [cobirds] Large Chipping sparrow fallout in OCS
While today is not the first time I've seen Chipping Sparrows this spring,
a large wave is coming through El Paso County this morning - I saw at least
80 on a walk through the Shooks run neighborhood, and they just keep coming
into our yard in groups of 20-40.

Observation start time: 07:45:00

Total observation time: 9.5 hours

Official Counter: Dustin Kohler

Observers: Dave Erickson, Deborah Hebblewhite, Marianne Erickson

Visitors:
We had 35 visitors to the ridge today including a guy with a 3-legged dog
who was getting around fine and hiking around with him.


Weather:
The wind and clouds picked up as the day went on. Overall there was lots of
sunshine, and it was a mild day. There was a Haze all day today and
affected our visibility.

Raptor Observations:
Almost all of our migrants were very high, especially before the wind
picked up and the sun went behind clouds.

We had a Broadwing fly to the southwest after appearing from the south.
This bird dove and disappeared around Red Rocks. I didn't see another
Broadwing the rest of the day, but I still counted this as a migrant since
Broadwings don't nest in the Denver area.

One of our migrating Cooper's Hawks was our 2000th bird of the season. Our
hawk watch doesn't have the numbers other sites do, but we make up for that
with diversity.

In local news, one of our Red-tails came up and chased a Cooper's Hawk
south. This Cooper's might have migrated, but got scared back to the
South.

We had one local male Kestrel that caught a mouse and ate it on a telephone
pull near us. A different kestrel flew south much later in the day.

A Bald Eagle flew Southwest, and a Golden Eagle was attacked by something
small, brown, and blurry in the haze. I would guess too small to be a
red-tail.

Non-raptor Observations:
We had a Western Kingbird at the ridge today. We also had Blue Jay, Rock
Wrens, Mallards, American White Pelicans, and a lot of Blue-gray
Gnatcatchers.

Someone also turned thirty today. We only knew that when we saw a big 3 and
a big 0 balloon tied together and soar up high in the sky.

Predictions:
Tomorrow should be a warm day with strong winds. The clouds should gather
more and more as the day goes on. I expect good migrant activity.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Low numbers continue. Most migrating birds seem to be arriving about on
schedule; they are just arriving in small numbers. Caught our first Yellow
Warbler today, which is about right. Only 5 birds banded (plus recaught 6
birds banded earlier this season or before):

Downy Woodpecker 1
Yellow Warbler 1
Common Yellowthroat 1
Lincoln's Sparrow 2

We are banding Tuesday through Sunday (closed Mondays) through May 31,
weather permitting. You can register to visit on the weekends through the Denver
Audubon website. <https://denveraudubon.org/events/> (The first couple of
weekends are sold out, so sign up now if you are interested!)

Subject: [cobirds] BCAS Field Trip: “Mindful Birding” at Goshawk Ridge, May 16


Join Peter Ruprecht for this unique birding field trip whose theme,
"mindful birding," means that we will spend quiet time at each of several
stopping points to focus deeply on any birds that we are able to see and
hear. Rather than finding and identifying as many species as possible,
we’ll focus on appreciating the ones we happen across. Goshawk Ridge
provides exceptional scenery and a variety of high-quality habitats. Plan
on walking about two miles on gravel road.

Registration required. Limited to only 8 participants. RSVP *t**o *reserve
your spot after 6 pm on Monday, May 6.

Thursday, May 16, 7 am – 10 am

Official Counter: Dustin Kohler

Observers: Clay Gibson, Joy Sommerer, Lori Morton, Michael Cotter,
Mike Fernandez

Visitors:
We had 17 Visitors to the ridge today two of whom were from the UK.


Weather:
Today started as a warm, sunny day, and turned to a super windy, cloudy
sky. Rain was all around us by the end of the day, especially to the
southeast and distant west.

Raptor Observations:
Our migrants were high over the horizon until the wind picked up and all of
the migrants dropped lower. Only 8 Kestrels were seen before the wind
dropped them.

Everything seemed to struggle to get up the strong northern wind except the
peregrine falcon who effortlessly glided past us.

An immature red-tailed that migrated had dove a few times at a peregrine
that was also migrating.

Some of our migrants are starting to be missing feathers on their journey,
especially juvenile birds getting their adult plumage.

In local news we had plenty of local Red-tails, one being an immature, a
local Peregrine Falcon, that was diving at a raven on its way south, a Bald
Eagle, a Ferruginous Hawk, a Swainson's Hawk, and a Sharpshin who wasn't
local on purpose as the wind prevented this bird from flying north.

Non-raptor Observations:
We had a Common Raven that was flying around with bread in its mouth. It
could have been a rock, but we think it was bread.

We had a flock of 10 Franklin's Gulls fly North but later had 40 more gulls
fly southwest in the strong headwinds.

Uncommon to the ridge/ other birds seen were, Yellow-rumped Warblers,
Blue-gray Gnatcatchers, Cliff Swallow, Orange Crowned Warbler,
Double-crested Cormorants, Mallards, and Broad-tailed Hummingbird.

There were lots of swallows and swifts passing through during the stronger
winds.

Predictions:
Tomorrow looks to be a sunny day that gets cloudier as the day goes on. The
wind appears to be fairly steady in an overall eastern direction.

Subject: [cobirds] Banding at CSR, El Paso Co., Wed
Hey COBirders,

The Bird Cast prediction last night was for an impressive migration flight. It may have been, but not many stopped at Clear Spring Ranch (at least in my area), and the ones that had been here, left! (Especially the over-wintering White-crowned Sparrows - I have had flocks around for 10 days, but only saw one today!) Real quiet, real slow.

I only banded 11 birds today - but the lack of numbers belies the diversity of what did arrive.

First-of-Year Blue-gray Gnatcatcher (Ad)
FOY Wilson’s Warbler - SY (second year) F
FOY female Common Yellowthroat - AdF (I have been catching males for a week)
FOY Brown Thrasher - Ad
FOY Green-tailed Towhee - SY
FOY Clay-colored Sparrow - SY
also banded 2 Lincolns Sparrows - Ad, and Com Yellowthroat - SY M

and saw only FOY Black-chinned Hummingbird M

Happy Migration,
Steve Brown

Weather:
Pleasant, light winds from the East though late morning the clouds

strong West winds with the clouds moving East.

Raptor Observations:
I filled in as counter today for the official counter who was ill.
Most of the migrant raptors today were seen far to the west and high, with
a small number overhead – either just east or west of the watch.
Interestingly 2 GE flew over Green Mountain to the east.
Highlights today were 3 dark morph Broad-winged Hawk of a total of 11 seen,
3 Ferruginous Hawk, 2 adult Swainson's Hawk – one which was low enough
to identify as a female (dark brown bib cf. rufous bib in a male), and a
group of 10 TVs migrating together in the 1st hour.
Non-migrant raptors: juvenile Golden Eagle, adult GE which landed in a tree
on Greene Mountain; a Sharp-shinned Hawk which flew East; an adult male
Kestrel feeding on the wing in the morning flying from west to east behind
the trees to the south of the watch and could not be found again, as well
as well as in the afternoon perched on a wire west of the watch; Red-tailed
Hawk 6, 18 TV sightings.
Liza and I lead a DFO trip this morning with 5 participants, 1 of whom was
Rajkumar Manikandan with his youthful eagle-eyes was helpful in in finding
us a number of raptors.

Non-raptor Observations:
Yellow-rumped Warbler 2, Spotted Towhee, Woodhouse's Scrub-Jay 2,
White-throated Swift c. 15, Black-capped Chickadee.

Predictions:
This reminds me after the 1929 stock market crash called something like
"What I've learned about the stock market" and it was a blank book! So also
my ability to predict at this site.

Report submitted by Official Counter (<j.f.peters58...>)
Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Subject: [cobirds] Re: House Wrens, Boulder County
Chuck, your wren needs to get together with a House Wren that was just
looking into one of my bird boxes. As the wren peered into the box, it gave
a low chatter— a pair of Black-capped Chickadees have been going in and out
of the box (was one in the box?).

Because I haven’t heard a wren singing, I suspect that “my” wren is a
female.

From: Jared Del Rosso <jared.delrosso...>
Subject: [cobirds] 1...2...3...Eastern Phoebes + a Bushtit's Buffet (Arapahoe)
I've made weekly visits to the High Line Canal in Greenwood Village /
Centennial (not far from the HLC Conservancy office) to observe a pair of
Eastern Phoebes. They've mostly been hard to find -- quiet and seemingly
reclusive in the chokecherries, plums, crabapple, cottonwoods, and vines
along the Canal. It took me about an hour to briefly spot one last week.

Today, the pair was incredibly vocal (around 7 AM). They were interacting a
lot, though I didn't see any apparent nest building activity or other signs
of breeding. I thought, perhaps, that they were merely readying for these
by increasing bonding activity.

But then they showed me what had them agitated: a third Eastern Phoebe, a
male, who they chased madly, but eventually gave up on. He gave the
"phoebe" call when they let him. He moved slightly up the Little Dry Creek,
toward private property, away from the pair after being chased.

Having a pair show signs of wanting to nest has been surprising enough. To
encounter a third was a shock. Might he draw a fourth? Might they find
another place to nest? (I kind of doubt it, but who knows.) And what does
this mean for the Western Flycatchers who nest along the Canal and Little
Dry Creek?

Intrigue.

For reference, I first encountered the male Eastern Phoebe on 3/28 with
students from DU. I first noticed that he was joined by a female on 4/15.

During last week's visit, when I struggled to find one of the Eastern
Phoebes, I encountered and was able to photograph, rather closely, a female
Bushtit gobbling up prey (scale insects, maybe, but I welcome corrections).
A few of the photos are on my blog
<https://lonesomewhippoorwill.com/2024/04/30/the-ferocity-of-a-bushtit/>.
(Google Groups gives me all kinds of trouble when I try to embed more than
one photo, and I often lose my posts.)

Subject: Re: [cobirds] SW Denver Turkey(s)
There have been multiple reports, and photos, of turkeys in the Denver
metro area on NextDoor. Many of the photos show a pair of turkeys. Same
turkeys traveling a fair distance or multiple turkeys?

Observation start time: 08:00:00
Observation end time: 17:00:00
Total observation time: 9 hours

Official Counter: Dustin Kohler

Observers: Bill Young, Mike Serruto, Nancy Cornick, Ryan Gannon,
Shannon Campbell, Shay Lyons

Visitors:
We had 22 visitors to the ridge today which is not too bad for a Monday.


Weather:
Today was a warm partly cloudy day with a constantly changing wind. Once
the wind picked up the migrants dropped.

Raptor Observations:
Our migrants continued to behave in classic dinosaur ridge fashion, either
super close to our heads or very far away. Generally, they dropped as the
wind picked up in the evening.

Three Broadwings were in a loose kettle. An immature Red-tailed had
see-through or missing middle rectrices (tail feathers).

Another Red-tailed hawk was attacking a Golden Eagle today, but this Golden
Eagle was a local and moved off to the west.

We had a Cooper's Hawk flying with a full crop and was carrying a mouse in
its talons. This hawk did not migrate and flew off to the west probably
where their mate was on eggs.

We had a Sharp-shinned Hawk fly south through or slightly around the
central tree on our platform between me and some of my volunteers.

We had another local Sharp-shin, a Swainson's, a Cooper's, a hunting
Kestrel, an osprey, and a Golden Eagle.

Non-raptor Observations:
We saw a man walking 4 llamas on a leash along the side of the road.

When I first got up to the ridge there were three Rock Wrens singing
nearby. Around 13:30 MST we saw a Rock Wren holding a stick in its beak and
is hopefully making a nest in the Northwest corner of our platform.

There were also a lot of White-throated Swifts and Swallows flying around
today. A few Broad-tailed Hummingbirds were flying past as well.

Predictions:
Tomorrow should be a warm day and very sunny. The wind should start in the
south and move to the west. I expect migrants to be very high and moving
pretty fast.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Subject: [cobirds] SW Denver Turkey(s)
My wife came across a posting on the Harvey Park neighborhood (SW Denver,
Denver Co.) Facebook page from a couple of days ago with a picture of a
young hen WILD TURKEY in someone’s yard, at least it certainly looked wild.
Then today (Mon., 29 Apr’24) we came across another (?) young hen in the
Athmar Park neighborhood not far from Huston Park, and seeing her live saw
no signs of domestication with classic and clean Wild Turkey plumage and the
sleek build of a wild bird. Presumably this same gal just showed up as a
“Lost Turkey?” on our Athmar Park Facebook page at Aspgren Park (W
Exposition & S Lipan) about a ½ mile from where we saw her/one; cropped
photo from Facebook attached. Has anyone else in the Denver urban core seen
any turkeys this year? Defnitely a strange one!

Total observation time: 10 hours

Official Counter: Dustin Kohler

Observers: Audrey Anderson, Isaac Leb, Lily Douglas, Marirosa Donisi,
Natalie Uschner-Arroyo, Pam Moore

Visitors:
We had 45 visitors to the ridge today. We had a visitor from Miami running
along the trails. We also had a visitor from Sacramento, California named
Lily Douglas who helped us spot for a few hours as she was waiting for her
evening flight.


Weather:
Today started off cloudy and remained partly cloudy for the rest of the
day. The wind shifted direction constantly until about 4:30 MST, then it
was a northwestern wind with 20+ mph gusts.

Raptor Observations:
Migrants started pretty low and close and got higher/ further away as the
day went on. After the wind picked up the migrants got lower and struggled
to move up the headwind.

The Ferruginous hawk was a dark morph. At first glance I thought it was a
Golden Eagle, based on size, but after looking at her (most likely) again
the tail was a uniform white color and the tucked bicolored wings lacked
the darker trailing edge of the Golden Eagles wings.

Our migrant who was an actual Golden Eagle was being chased north by 2
red-tails and a couple of Ravens. One of the Red-tails was an immature
missing 3 primaries. The other particularly aggressive Red-tailed chased
this Eagle far to the south and then turned around and chased the Eagle
back to the North and out of sight.

At about 9:30 MST a Sharp-shinned Hawk flew by and dove into a juniper
tree. We heard a surprised squawk from a Chipping Sparrow as the
Sharp-shinned flew off empty-taloned into a nearby tree to pout before
flying off to the south.

There was also a male and female pair of local Cooper's Hawks. 2 Golden
Eagles, and a different local Sharpshin. I'm not sure that the accipiters
were local, or if the wind prevented them from moving on.

Non-raptor Observations:
Today we saw a lucky Chipping Sparrow, Rock Wren, Western Meadowlark,
Spotted Towhee, American Crow, Western Bluebird, Blue-gray gnatcatcher,
Black-capped Chickadee, Violet-Green Swallow, Tree Swallow, Barn Swallow,
White-throated Swift, Woodhouse's Scrub-Jay, Double Crested Cormorant, and
Eurasian Collared Dove.

The Swifts were having trouble flying in the wind at the end of the day.

Predictions:
Tomorrow should be another warm, partly cloudy day. I expect a dryer trail
and similar migrant numbers to today.

Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.

Official Counter: Dustin Kohler

Observers: Chris Gearhart, Dave Hill, Guillaume Stordeur,
Joyce Michael, Karl Brummert , Natalie Uschner-Arroyo

Visitors:
We had 41 visitors to the ridge today including 5 ladies in a hiking club.
Their birding friend was out of town, so they said that they will be back
with this friend. Another guy said he would come back and bring his wife
and daughter.


Weather:
Today started a fairly cloudless and warm day. The wind started from a
Northwestern direction but switched to West and Northeast throughout the
day. At about 11:15 MST there was rain to the South, and at about 14:30 MST
wind picked up and the rain started.

We called count early because of close thunder overhead, the storm and/ or
rain is to continue the rest of the day and turn into a winter weather
advisory tomorrow.

Raptor Observations:
Our migrants were either very close overhead or miles away. The medium
distance that we usually see migrants, didn't have any migrants today.

The Northwestern wind kept our smaller migrants (kestrel, sharp-shin,
cooper's) mostly stayed low to the ridge or the other ridges, but our other
migrants were generally higher up, out of unaided vision.

The Goshawk was molting from its juvenile plumage to adult plumage. This
particular bird had a swallowtail look as, its middle rectrices were still
growing out. The wings looked like adult wings, but there were some
juvenile feathers on the chest.

The unknown accipiter was either an immature Cooper's or an immature
Goshawk. The flaps were strong and the tail seemed almost extra long
suggesting a goshawk, but the wings seemed less bulky and there was a lot
of head projection suggesting a cooper's. After consulting many books we
still could not get a definite ID.

The Broad-wings were very far away their wings looked like accipiters, but
with very little tail. This combined with the three in a kettle together
suggested Broad-wings.

Local news was pretty slow. We had a local Cooper's hawks and several
Red-tails including one who was parading around with a big vole.

Non-raptor Observations:
We saw a Mule and an Elk in velvet as their antlers are growing back. We
also saw a big bumblebee with a thick orange stripe on its abdomen.

There were a lot of Swifts playing in the wind, and three types of swallows
(Tree, Violet-Green, and Northern Rough-winged). There was also a
red-breasted nuthatch, blue-grey gnatcatchers, rock wren and our usual
spotted towhees and western meadowlarks.

Predictions:
There is a Winter storm warning from 3 am Saturday to 6 am Sunday. With
4-12 inches of snow and precipitation all day. Tomorrow is likely to be
canceled.

Subject: [cobirds] Re: THE LONESOME WHIP-POOR-WILL: THE UNTOLD STORY OF AMERICA'S MOST ICONIC BIRD
Just a little plug -- I'm super excited to share this work with the Denver
birding community! If you're able to attend, you'll see a few remarkable
videos and photos of Eastern Whip-poor-wills and Common Poorwills, which
biologists who work with these species were generous enough to permit me to
use. I'll also describe Whip-poor-wills in 5 words (kinda sorta), two of
which are rarer things than spotting a Whip-poor-will. And I'll share with
you some of the lore surrounding the year's first Whip-poor-will and some
of the early accounts (from the 1950s) of people documenting the species'
decline.

The presentation is well-timed, too! Poorwill are returning to the Denver
metro area (and there are already reports of them). So you can go out the
next morning or evening and try to hear your own first-of-the-year nightjar.

Subject: [cobirds] Bird Conservancy of the Rockies - Chatfield Banding Station, 4/26/24
We only caught 5 new birds today, but we recaptured 8 birds that had
already been caught this season, so the early morning DFO trip, led by
Charlie Chase, got to see up close a variety of birds, including year round
residents (Black-capped Chickadee, Song Sparrow, Bushtit), possible summer
breeders (Common Yellowthroat), winter resident (Gambel's White-crowned
Sparrow), and migrants passing through (Orange-crowned Warbler, Lincoln's
Sparrow).

The 5 new birds were:

Black-capped Chickadee 1, banded 2022
Bushtit 1
Orange-crowned Warbler 1
Song Sparrow 1
White-crowned Sparrow, Gambel's 1

We are banding Tuesday through Sunday (closed Mondays) through May 31,
weather permitting (which means we may be closed tomorrow/Saturday). You
can register to visit on the weekends through the Denver Audubon website.
<https://denveraudubon.org/events/> (The first couple of weekends are sold
out, so sign up now if you are interested!)

Subject: [cobirds] Bird Conservancy of the Rockies, Pineridge Banding Station, 4/25 and 4/26
We set up nets at Pineridge Natural Area in on the north end of Dixon
Reservoir (Fort Collins, Larimer County) just yesterday, and got in a few
hours of banding. Today we opened nets just prior to sunrise and continued
for about 4 hours before the wind picked up and shut us down a bit early.
Across these two days of just a partial effort, we banded 36 birds of 10
species. We've had good numbers of Yellow-rumped Warblers moving through,
along with a few Orange-crowned Warblers mixed in, but no other warblers
thus far. Here's the summary for April 25th and 26th combined.

Red-shafted Flicker - 1
European Starling - 2
American Robin - 3
Yellow-rumped Warbler - 12 (5 Myrtle, 5 Audubon's, 2 intermediate)
Orange-crowned Warbler - 2
American Goldfinch - 9
Spotted Towhee - 1
Lincoln's Sparrow - 3
White-crowned Sparrow (Gambel's) - 1
Red-winged Blackbird - 2

We are anticipating being closed tomorrow (April 27th) due to the forecast
for heavy rain. Our lead bander this spring season is Camille, keep an eye
out for her reports next week!

This banding station will be operating Tuesday through Saturday until May
30th, weather and trail conditions
<https://www.fcgov.com/naturalareas/status> permitting. Visitors are
welcome and can register here

Official Counter: Dustin Kohler

Observers: Dave Erickson, Gary Rossmiller, Janet Peters,
Josephine Tongestad, June Peters , Marianne Erickson,
Mike Hunter, Steve Ryder , Trenton Voytko

Visitors:
We had 20 visitors to the ridge today including Mike Hunter who was
visiting from England and saw his 7,000th bird which was an American
Goshawk.

We also had 2 visitors from Belgium.


Weather:
Today started as a warm cloudless day, and turned into a thunderstorm. The
wind was out of the East/ Northeast all day. There was a heavy haze all day
that affected our distant visibility.

Count was cut short due to lightning risk. I was going to wait it out, but
with only a few hours left it started to rain/ sleet/ hail and I canceled
the rest of the count.

Raptor Observations:
Today was our best day of the year, so far with 128 migrants! They started
very high and/or far to the west. About 11:45 MST the wind picked up and
the migrants got lower and lower as the day went on.

The Unknown Falcon was probably a kestrel, but I never saw it and it just
zipped under a volunteer on the far side of the ridge from me.

The Unknown Accipiter was far away, the tail was long, but it didn't flap
and was too far away to guess Cooper's vs Sharp-shinned.

In local news, we had a few Red-tailed Hawks, two Osprey, a local Golden
Eagle, 2 local Swainson's Hawk one was a Juvenile, an immature American
Goshawk, but the coolest was a leucistic Red-tailed that showed up many
times.

Non-raptor Observations:
We had my first to the ridge Blue Jay, and our first of the year, Blue-grey
Gnatcatchers.

The strong winds had a lot of White-throated Swifts and three species of
Swallows. Tree, Violet-green, and Barn.

Predictions:
Tomorrow looks to start partly cloudy with strong western winds, and change
to thunderstorms in the afternoon.

A partial count is likely.

2 returns:

Orange-crowned Warbler 2
Spotted Towhee 1 new, 1 banded 2021

>> I would like to share a few thoughts about the list for clarity in terms
>> of its goals and what expectations we might have for it.
>>
>> This list is a collective effort to discover and document how many of the
>> species on Colorado's official state bird list have been observed,
>> identified, and recorded from a yard. It highlights the incredible
>> diversity of yard habitats in Colorado, our remarkable breadth of coverage
>> of Colorado's avian species, and the value of birding in the ultimate of
>> local patches, our yards. I hope this list will continue to grow, be an
>> interesting resource, and be a fun way of connecting with other birders
>> across the state.
>>
>> One of the main goals is to reflect the communal effort by ensuring that
>> everyone's contribution is in some way represented and recognized. As much
>> thought and care as there was put into the matching of species and viewer
>> (method outlined below), it wasn't possible to pair everyone with each of
>> our favorite, or most memorable species. The answer to this is the
>> Additional Sightings feature in Column H, which gives the option of adding
>> one's name and sighting to species that are personally meaningful.
>>
>> You'll notice the absence of dates on the list. This is something Bryan
>> and I debated about, and eventually decided not to include due to various
>> challenges and considerations. One challenge is that many of us keep
>> yardlists without dates of sightings, or just general "Summer of '73" kind
>> of notes. If there is enough interest in adding this data set, we could add
>> an editable column for it.
>>
>> The current list total of 400 species reflects the uncertain status of
>> two species: Tundra Swan and Glossy Ibis. Both species required leaving the
>> yard to confirm the ID, something that would be potentially permitted under
>> Big Sit rules, but perhaps not acceptable under the most inclusive yard
>> listing rules. My initial response was to include them. But then I had
>> second thoughts. Perhaps it would be best to leave them off the list,
>> unless there is overwhelming support to include them.
>>
>> While there is no formal review (a la eBird or CBRC), the intent is to be
>> as accurate and pure as possible. As new species are added to the list, it
>> would be ideal, especially for rare species, for contributors to include a
>> link to an eBird or CBRC report.
>>
>> It's worth mentioning that this list is neither intended nor set up to be
>> a database for complete yard lists.
>>
>> **If you happen to notice a species with "Viewer" listed as Anonymous
>> that you believe is actually your sighting, and you would like to have your
>> name listed, please let me know and I will make the changes. This would
>> really only apply to sightings of species sourced from CBRC and eBird
>> reports.
>>
>> **If you ticked off a species on Bryan Guarente's Google sheet, but don't
>> see your name listed here, and would like your sighting to be included,
>> please consider using the Additional Sightings feature in Column H
>> (instructions for data entry below).
>>
>> **If there are any first state record sightings on this list that happen
>> not to be attributed to the original viewer, please let me know. It would
>> be nice for the original viewer to receive the recognition.
>>
>>
>> *A Brief Overview:*
>>
>> There are three sheets:
>>
>> 1) The list in Taxonomic Order
>> 2) The list in Alphabetical Order
>> 3) A Needs List in both Taxonomic and Alphabetical Order
>>
>> You can navigate from one to the other by clicking on the tabs at the
>> bottom margin.
>>
>>
>>
>> *The Link:*
>>
>>
>> https://docs.google.com/spreadsheets/d/1GNxdFNOXy1767VMnnQkUulrzszSycvvVz8BBkErzNWA/edit?usp=sharing
>>
>>
>>
>> *The Taxonomic List: The Place to Add Data*
>>
>> The Taxonomic List is set up so that data may be entered for new species
>> (the blank cells in Columns D-G). If you have any species to add to the
>> list, please feel free to enter the information in the
>> appropriate cells. It would be great to have complete information on each
>> species (Name, City, County) rather than just a tick. Links to eBird
>> reports and/or photos would be terrific, especially for the rarer species.
>>
>> If you would like to remain anonymous that's totally fine, of course. I
>> would just ask you to consider sharing your sighting with me directly via
>> email (I will not share any names), just to have some way to verify that
>> it's an actual sighting (and not bot generated 🙂).
>>
>> Data that's already entered in Columns A-G is protected. Please let me
>> know if you see any errors, misspellings, etc in the data already entered.
>> I'll be happy to make corrections and edits.
>>
>>
>>
>> ***Column H: **Additional Sightings***
>>
>> Detailed instructions (with screenshots) on how to enter data to come in
>> a separate email, but here is a not-so-brief description of how to enter
>> additional sightings.
>>
>> Notice that each cell in Column H (for species currently listed/ticked)
>> has a small downward facing arrow along the right margin. Clicking on this
>> arrow reveals a dropdown list. I've set up several as examples.
>>
>> 1) Click on the small downward-facing arrow. This will reveal a short
>> list of names & counties, or "Option 1", "Option 2", or a combination of
>> the two. Below this, in the bottom right corner, is a small pencil symbol
>> (otherwise known as the "Edit button").
>>
>> 2) Click on the pencil symbol. This will open a sidebar along the right
>> side of the browser window with the heading "Data validation rules." From
>> top to bottom, you will see "Apply to Range" & "Criteria" and corresponding
>> cells. Ignore those, no changes necessary. Below that you will see cells
>> that contain "Option 1" or "Option 2". If both Option 1 and Option 2 boxes
>> have been filled out with other observations, you may click on the box that
>> reads "Add another item" in green text.
>>
>> 3) Click on the first available cell, delete the text that says "Option
>> 1" or "Option 2", and replace it with your name and county (example: Thomas
>> Heinrich, Boulder).
>>
>> 4) Click on the green "Done" button at the very bottom of the sidebar. A
>> pop-up window will appear, which will ask* "Apply to all? There are ###
>> other dropdowns with the same properties, do you want to make changes to
>> all of them?"*
>>
>> 5) Be sure to click on the "Just this instance" button only please 🙏,
>> otherwise potential chaos. If you accidentally click on "Apply to all", you
>> can undo the mistake by pressing the Command and Z keys simultaneously.
>>
>> 6) After clicking "Just this instance", you'll notice that the cell still
>> appears blank. Click on the small arrow one more time. This will reveal the
>> dropdown box again, this time including your name & county. Click on your
>> name & county. The cell will now list your entry, and you're done.
>>
>> Note that this dropdown feature allows one to toggle between the various
>> additional sightings for each species. Anna's Hummingbird, for example, has
>> been seen in five yards. The Primary viewer is listed as Bill Schmoker,
>> with additional sightings from Rachel H, Tina J, David S, and Brad B. At
>> the moment, Rachel H, Larimer is displayed in Column H. But Tina, David, or
>> Brad might like to have their name appearing in that cell at some point,
>> and use the dropdown feature to select their entry.
>>
>>
>> *Links to Colorado Bird Records Committee or eBird Reports (Column I)*
>>
>> An option for those wishing to share a link to a CBRC or eBird report of
>> a personal sighting. Please provide links only to sightings of your own,
>> out of respect for others' privacy or desire to remain anonymous. At the
>> moment, the list is set up with space for only one link per species. (This
>> could be adjusted if there's interest in having more than one link per
>> species.)
>>
>>
>>
>> *Links to Photos (Column J)*
>>
>> An option for those wishing to share a link to a photo of a personal
>> sighting. I've entered one for a Northern Pygmy Owl from my yard as an

>>
>>
>>
>> *The Alphabetical & Needs Lists *

Subject: Re: [cobirds] Mystery dove song at Golden Ponds
Folks,

I do not believe the Longmont mystery bird is a White-tipped Dove. At least
it's not a typical one.

I probably spend 5-10 days in White-tipped Dove's range in an average year.
The candidate sound that people are hearing a resemblance to is what I call
the "Growl Song" of White-tippped Dove. This is much less common than the
regular song and apparently given in courtship situations. (Almost all
North American dove species have some kind of raspy, growling, or trilled
courtship song.)

Here are four examples of White-tipped Dove's Growl Song:

1. The second recording at this link:
https://www.allaboutbirds.org/guide/White-tipped_Dove/sounds (linked
earlier by Matt)
2. https://xeno-canto.org/277692, also linked earlier by Matt;
3. The two "Growl Song" examples at petersonbirdsounds.org

Note the distinctive rhythm of the Growl Song: *short-long,
short-short-short-long*, with every note trilled except the last two (the
second-to-last note is sometimes partly trilled). The last two notes
(short-long without a trill) resemble the species' regular song. Everything
pretty much happens on one pitch, except the long notes are lowest in the
middle.

It's important to note that *in every example of the White-tipped Dove
Growl Song, the rhythm never varies much*. This is universal among doves.
They don't learn their songs, which means their songs don't usually vary
much geographically or between individuals. We can expect all normal
White-tipped Doves to deliver the same Growl Song with more or less the
same rhythm and the same distribution of trilled and non-trilled notes,
just as all White-winged Doves sing "Who cooks for you?" in their Short
Song and "Who cooks for you, Julie? Who, Julie? Who?" in their Long Song.

The Longmont mystery bird does sound like a dove, and I can certainly hear
the resemblance to White-tipped in tone quality, but the rhythm and
distribution of trilled vs. non-trilled notes are way off. Part 1 of the
song appears to be a single long, overslurred trill that almost recalls a
screech-owl trill. Part 2 of the song seems to be a non-trilled 4-note
short-short-short-long pattern, each note higher than the last. Neither
song part lies within the bounds of White-tipped Dove variation. I can't
match it to any dove species I know. My best guess would be a hybrid or an
exotic of some type.

It's definitely a tremendously interesting recording. Kudos to Jamie Simo
for noticing that it was weird and getting audio documentation. People in
the area should keep their ears peeled in case this thing shows up again
and starts singing. I would LOVE to know what is making this song.

Official Counter: Emma Riley

Observers: Bill Young, Chip Dawes, Clay Gibson, Karen Fernandez,
Ric Olson

Visitors:
We had another great day on the ridge with 47 visitors today including a
birder from England looking for his 7000th life species. Thank you to all
that showed up today and helped spot and keep track of our crazy day, both
on and off our volunteer schedule. I am expecting another busy day
tomorrow.


Weather:
Today was a hot one with scattered clouds but rarely clouds covering the
sun. Winds stayed pretty consistent all day today from the general E
direction. Humidity was low and in the last 2 hours a pretty thick haze
settled into the west valley.

Raptor Observations:
The second I got to the ridge today migration was off with a bang with our
best BW day and overall day this season! We had small kettles of 2-5 BW
moving consistently for the first hour and then they continued to come one
by one for much of the morning, dwindling off throughout the day. At one
point we had 4 BW, 1 RT, and 1 FH all in the same kettle. We did get to
see one BW in the last hour of the day as well. We are also seeing SW
moving throughout the day and expect this to continue. Migration as a whole
is truly in its peak currently and we are loving it!

Local RT activity was high and steady all day with up to 6 seen up at one
time. We continue to see 5 local TV moving around the western ridge. We
also saw the local PG, GE, AK, and CH today.

Non-raptor Observations:
Spring migration has also picked up for passerines as we continue to see
FOY birds, with todays being both WBNU and RBNU. Other passerines seen or
heard today include BTHU, BCCH, WEME, SPTO, WTSW, BARS, VGSW, CORA, and
others. WTSW activity was not as high as it has been in the last few days
but they were still active. It goes without saying that the CORA continue
to be active through the day.

Predictions:
Tomorrow morning will be sunny with winds from the SE. Rain is possible in
the afternoon, potentially kicking off our predicted rainy weekend. As
always I cannot promise anything, but am hopeful for more BW in the
morning.
========================================================================
Report submitted by Official Counter (<j.f.peters58...>)
Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

The plot thickens.

Please note that visitors to Chico will need to *sign Chico's waiver at the
HQ kiosk.* That's all you'll need to do at the kiosk.

Thank you.

Subject: [cobirds] Bird Conservancy of the Rockies - Chatfield Banding Station, 4/24/24
We had a beautiful morning for opening day of 2024 banding at Chatfield.
Spring is early - there are bushes flowering a week or more earlier than
usual. Towhees and chickadees competing to see who can make the most
noise. Pelicans soaring overhead. A Downy Woodpecker hung out at the
banding station most of the morning, which was a treat for our 4th grade
visitors.

We caught 15 birds which included all the usual first day species:

Black-capped Chickadee 4 new, 1 banded 2019 as an adult, so hatched 2017
or before.
House Wren 1
Common Yellowthroat 1
Spotted Towhee 1
Song Sparrow 4
Lincoln's Sparrow 1
White-crowned Sparrow, Gambel's 2

Reports on our 2021 and 2022 banding seasons can be found here
<https://www.birdconservancy.org/what-we-do/education/bird-banding/> on our
website. With any luck (!!) I will get 2023 posted in the next week or so!

We are banding Tuesday through Sunday (closed Mondays) through May 31. You
can register to visit on the weekends through the Denver Audubon website.
<https://denveraudubon.org/events/> (The first couple of weekends are sold
out, so sign up now if you are interested!)

Subject: [cobirds] Clear Spring Ranch, El Paso Co., Wed
Hey COBirders,

On a beautiful spring morning at CSR (cool, clear and CALM!), migrants are starting to arrive!
First thing, I banded an FOS House Wren adult - could be arriving to breed, or passing through, then about 9:00
a flock of Audubon’s Yellow-rumped Warblers passed through, working the catkins high in the cottonwoods (alas - uncatchable).
I also banded a dozen sparrows (Song, Lincoln’s, one Mountain White-crown, and lotsa Gambel’s White-crowns). Three recaps from 2022 and 2023, and the wintering white-crowns are about 95% done with molting from juvenile brown to their adult white-colored crowns. They will be leaving soon.

It is just starting to green-up at CSR, - on cottonwoods and golden currant, but hardly any green in the ash trees or coyote willows yet.

Happy Migration,
Steve Brown
Colo Spgs

Interesting, Jamie! I listened closely to the recording, and can hear a
trilling occur before all three of the calls in the recording.
At this link: https://www.allaboutbirds.org/guide/White-tipped_Dove/sounds,
check out the second recording, which includes a similar trill before each
call. Also on several recordings on Xeno-Canto from birds in Texas, like
this: https://xeno-canto.org/277692

The trill in Jamie's recording sounds too low to resemble anything else I
can think of that trills.

I'm interested to hear what others think of this recording, and the
possibility that Jamie recorded a White-tipped Dove?

Visitors:
We had another great day of visitors on the ridge today with a few in
search of BW and about half of them being successful. As always thank you
to our volunteers and visitors for helping spot birds! Happy 13th Birthday
to our youngest observer, Archer S. Thank you for choosing us to spend your
afternoon with us! We had a total of 38 visitors on the ridge today with
many of them stopping to ask questions and hang out to try their luck at
seeing a migrant. Our volunteer Dave Erickson brought our honorary
observer, Prairie the Bernese Mountain Dog, up for a quick visit today.
Thank you Dave, she is my favorite.


Weather:
Today was a bit cooler than yesterday but we had excellent viewing
conditions again with 50% or higher cloud cover all day. Winds were from
the E in the morning but started to vary in the afternoon. We got drizzled
on for no more than 10 minutes in the afternoon.

Raptor Observations:
The day started out with something I haven’t seen at this site before, a
push of 5 OS back to back to back in about 20-30 minutes. We had one non OS
move between them but other than that it was an OS start to the day.
Migration stayed pretty consistent today with our lowest hour seeing 5
migrants. BW continue to move and had a nice push in the early afternoons.
We also saw a nice little push of SW in the late afternoon. As always we
got to enjoy our “5 o’clock falcon hour” with very close AK coming
one after the other.

Local raptors seen today include BE, GE, RT, TV, SW, and PG.

Non-raptor Observations:
Spring has sprung for our passerines with FOY WEME, BTHU, WTSW, VGSW, BARS,
BBMA, WOSJ, SAPH, CORA and others seen today. We had two groups of AWPE
today, one of 5 and one of 30. The swifts & swallows have been out en masse
dominating the sky for the last few days, confusing us at times with tiny
speedy AK.

Predictions:
Tomorrow will be warmer than today with party cloudy conditions and
variable winds but some SE winds predicted. We are expected to get more
precipitation in the area this weekend. As always, I cannot promise
anything, but I’m hopeful for some more BW and SW tomorrow. Bring your
sun hat and optimistic attitude and we will see you on the ridge!

I was at Golden Ponds in Longmont this morning and in the back corner by

blowing a recorder because it had that quality to it. The Merlin app didn't
ping on it, but I did get a recording. I'm not sure if Cobirds will allow
the link, but here goes nothing. You can hear it best at 1:49, 2:44, and

I couldn't locate the bird to see it, but the closest song to this that I
could find is White-tipped Dove. Am I crazy? Is this just a weird Mourning
Dove or Eurasian Collared-Dove?

Subject: [cobirds] Chaetura Swift Help
Hello Everyone,

I would like to start a conversation about Chaetura swift identification in
light of the recent Vaux’s Swift reports from Valco Ponds. I find that this
is an extremely difficult and underrated identification question, and I
would love to hear comments from the community to help clarify my own
thoughts. I also hope this discussion can be an opportunity for everyone to
dig into an ID topic that is rarely studied in colorado!

I recently spent some time observing the swift(s) present at Valco Ponds,
and found myself unable to confidently place the bird in the Vaux’s
category. There are a myriad of factors that go into this difficult ID, and
I think that many of these traits are quite variable. I have listed my
thoughts on each identification trait generally used in Chaetura swift ID
below.

First, per eBird bar charts, Vaux’s Swift should not be considered the
expected swift during the third week of April. Chimney Swift has been
observed in Colorado as early as April 9th, and I have personally heard
them calling on the plains as early as April 23rd. I think it’s important
to note this so that we don’t go into this ID with a potentially biased
judgment.

Secondly, in terms of physical structure, I have read that a consistent
physical difference is that Chimney Swifts typically have longer, pointier
wings, and bulging inner primaries. This creates a pinched look where the
wing meets the body, which is less present in Vaux’s Swift. However, after
digging through many Chaetura photos on eBird, I’ve found that this almost
entirely depends on the angle of the photos. I feel that I can find photos
of both species having both wing shapes depending on what I want to see. If
a bird is pursuing aerial prey, they constantly change their wing shape,
and that distorts with the wing proportions. Additionally, there are also
documented differences in both physical size and flight pattern. I
personally was not able to observe the bird next to any other birds, but a
Vaux’s Swift should be about the size of a swallow, if not slightly
smaller. A chimney Swift should be slightly larger than the surrounding
swallows. If anyone was able to observe the bird in question with swallows,
I would love to hear about it! As for the flight style, Vaux’s are
considerably more bat-like in their flight, while Chimney Swifts have
longer slower strokes. I was not able to personally differentiate those
traits while watching the bird at Valco, but again, I would love to hear if
anyone saw something that they feel strongly indicates one way or the other.

Next, in terms of plumage, I noticed a lot of field notes stating that the
bird was IDd by a paler throat and a paler rump. This has been a purported
field mark for a while, but it is not an absolute trait, but rather a
gradient. Both Chimney Swifts and Vaux’s Swifts have pale throats, and it
is therefore important to look at this field mark in the context of the
entire underparts. Vaux’s swifts have low contrast throats because their
breasts are lighter, while Chimney Swifts actually seem to be the Chaetura
with higher contrast throats. This variability is also present in the
lighter rump trait, where many chimney swifts also show a light rump. These
traits seem to be highly dependent on the light conditions during
observation. I have included some photos of the Valco bird that show
potentially contradictory characteristics (potentially due to the lighting
conditions)

Low Contrast throat: https://ebird.org/checklist/S169344097

Higher Contrast Throat:

https://ebird.org/checklist/S169701997

https://ebird.org/checklist/S169742187

https://ebird.org/checklist/S169493238

Finally, I think that this ID problem is complicated by the possibility of
multiple birds currently residing at Valco Ponds. Some observers have noted
multiple birds on their checklists. I also believe that there are multiple
birds at Valco Ponds, as many of the characteristics I listed above vary
greatly between photos, differing more than I would expect for a single
individual.

If anyone has any additional photos that are not on eBird, I would also
love to see them! Fantastic work by Chris and Brandon for calling attention
to this bird, and great work by all those who took photographs!

I look forward to hearing your opinions and learning more about this
fascinating ID conundrum!

Best,

Luke Pheneger, Boulder

William Anderson, Erie

Subject: [cobirds] "White" Red-breasted Nuthatch in S Jeffco
I had a very interesting female Red-Breasted Nuthatch at my feeder today. With the naked eye her underside seemed pure white. When I first saw her, I thought it was a White-breasted. I have not seen her before. The other female who frequents has the pale rusty blush.

Observation start time: 09:00:00
Observation end time: 17:00:00
Total observation time: 8 hours

Official Counter: Emma Riley

Observers: Bill Young, Mike Serruto, Ryan Gannon, Shay Lyons

Visitors:
We had a great crowd up at the ridge this morning with folks in search of
BW and they were not disappointed! While looks at the birds could have been
better, everyone that came out to see them got to see them. As always I
want to thank our volunteers for their help spotting distant birds today.
We had a total of 44 visitors on the ridge today with many of them getting
to see migrants.


Weather:
We had excellent viewing conditions today with cloud cover all day and
partial sun. Winds were from the E in the morning and began to vary in the
late morning. Right around the 1300 hour winds picked up to speeds of 26
mph in gusts, continuing for the rest of the day. Rain could be seen west
of us in the late afternoon but missed us all day.

Raptor Observations:
Today was our biggest Broad-winged Hawk day to date with all but one of
them in the morning. There was an abrupt halt to their migration when the
winds picked up which was interesting to see but disappointing for our
afternoon volunteers. The smaller birds came en masse in the high winds
with AK, SS, and CH coming so close we felt like we could touch them.
Almost all of our birds today were over the west ridge, with the only
overhead/east birds coming in the afternoon high winds.

Local raptors seen today include RT, TV, GE, CH, OS, and AK. 7 TV at once
were seen around Mt Morrison in the afternoon not migrating.

Non-raptor Observations:
Passerine activity was low today, especially in the late afternoon, minus
the WTSW out in unbelievable numbers. We saw SPTO, SAPH, BARS, CORA, and
others today. 2 CORA were seen mobbing the late BE today, and looking
minuscule next to the eagle.

Predictions:
Temperatures are supposed to be lower tomorrow than they were yesterday but
our nice spotting conditions look like they will be sticking around for at
least part of the day. Migration has picked up and we are hopeful for some
more BW and SW tomorrow.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Subject: Re: [cobirds] Re: Chico Registration Opens Monday April 22nd! (El Paso, Pueblo Counties)
Hi folks,
Thanks to Linda for posting these details, and I wanted to add some
information about Bird Conservancy's banding station at Chico Basin Ranch.
We're planning on continuing to run the station for 5 weeks each spring and
fall.

- The banding station will be open 6 days a week (closed Sundays) from
April 29th through May 31st. The station is open until about 5 hours after
sunrise (weather permitting).
- Visitors are still welcome at the banding station during operating
hours, though registration through Aiken Audubon's system is now required
to access the site.
- We are still working with Ranchlands to host visiting school groups at
the banding station. School groups can register by contacting
<learning...> These visiting school groups, as well as any
on-site Bird Conservancy staff and volunteers, will not count towards
the 20-person daily visitor limit.

Any questions relating to the banding station at Chico Basin Ranch can be
sent to me, <colin.woolley...>
We are looking forward to spring birding and banding!

Visitors:
We had 53 visitors to the ridge today including my parents who came out to
visit from Missouri. Thank you guys again for helping out all day today.


Weather:
Today started as a very foggy, but otherwise sunny day before turning into
a blue sky full of sunshine. Towards the end of the day, it became more
partly cloudy.

The wind was gusty and out of the Southeast throughout the day.

Raptor Observations:
Our migrants started fairly low to the east or straight up, but then got
higher and either remained straight up or were to the west.

We had 16 of our 19 species migrate, but saw 17 out of our 19 throughout
the day, only missing Rough-legged and Ferruginous Hawks.

Almost all of our accipiters migrating had a full crop, at least the closer
ones.

Our first Bald Eagle was missing a secondary flight feather, and the
juvenile Bald Eagle looked very raggedy in terms of missing feathers.

One of our migrating Red-tailed Hawks had a white tail, and it's chest was
fairly white with a dark belly band. This bird was possibly a White-morph
Harlan's, but I am not sure.

Our unknown Falcon was probably a Merlin, but too far away to be sure. One
of the unknown Buteos was probably a Swainson's Hawk. The other unknown
Buteo and Accipiter were too far away to guess which member of their genus
they were.

In local/ non-migrating news, we had our usual Red-tailed Hawks, but we
also had a local Golden Eagle, Swainson's Hawk, Bald Eagle, Cooper's Hawk,
Peregrine (seen twice), and two different Northern Harriers.

Non-raptor Observations:
We had 3 Double-crested Cormorants and about 53 Franklin's Gulls migrating
a few hours apart. We also had White-throated Swifts, and at least 3
different species (Tree, Barn, Violet-green) of Swallows migrating
throughout the day.

Other passerines included: Broad-tailed Hummingbirds, Red-breasted
Nuthatch, Black-billed Magpie, Bushtits, Dark-eyed Juncos, Spotted Towhee,
Western Meadowlark, Northern Flicker, and a Rock Wren.

Predictions:
Tomorrow looks like a warm, partly cloudy day with winds out of the
Northwest. A good sky for viewing migrants, but join Emma up on the ridge
to see how that Northwestern wind affects the migrants.

Subject: [cobirds] Marbled Godwits - Union Res., Weld Co.
Took a quick run around southwest Weld Co. this afternoon (Sun., 21 Apr.'24)
to check for shorebirds. Most every spot had very high water as expected,
but needed to scratch that itch just to be sure. While shorebirding was
thin, there are always birds to find with the most fun coming at the end of
the day with a large flock (38) of MARBLED GODWITs along with five (5)
WILLETs on the north shore of Union Reservoir (Weld Co.). Other highlights
included several first-of-year species for me with FRANKLIN'S GULLs and a
nice FORSTER'S TERN at Prospect Reservoir (Weld Co.), Willets at three
different locations, and the always welcome return of SWAINSON'S HAWKs in
many spots.



While Union is also high, there is a decent shoreline on the north side so
still worth checking - the best shorebird habitat I ran into today. With
the Long-billed Curlews Susan just reported at the Arsenal, it's time to get
out and do some shorebirding of your own.



Good Birding,

Doug

Subject: Re: [cobirds] Re: Chico Registration Opens Monday April 22nd! (El Paso, Pueblo Counties)
All,

Apparently I wasn't very clear, as questions are rolling in.

The cost is *$15/person/day,* as it's been for years. There is no discount
for groups, as there has been in the past.

A group is meant to be for an organization, like DFO or Audubon
chapters, with 10-12 attendees. We may consider slightly smaller groups,
but it will depend on how busy it gets for our registration team, since all
of us work.

Please do let me know if anything else is unclear.

Subject: [cobirds] Brown Pelican at John Martin Reservoir, Bent County CO
Birders,


I found a Brown Pelican roosting on Dinosaur Island on the north side of John Martin Reservoir this morning. It was with about 20 American White Pelicans. Dinosaur Island is about midway between the the west and east entrances to the north side of the reservoir, and is about 4 miles west of the dam.


Photos will be posted later.

Observation start time: 09:45:00
Observation end time: 12:30:00
Total observation time: 2.75 hours

Official Counter: Dustin Kohler

Observers:

Visitors:
We surprisingly had 13 people visit the ridge today. In addition, a dog ran
up and tried to steal my sandwich, but I was cold and hungry and did not
share.


Weather:
Snows prevented us from getting up as early as usual, but there was a break
in the precipitation. After a few hours, the snow picked back up, the fog
rolled in, and the combination would have made visibility near zero km. At
that point, I canceled the rest of the count.

Raptor Observations:
With bad weather the last 3 days, migrants seemed to be waiting for a lull
in the snow to make a break north. All of our migrants were low either
above me or to the east.

We had a dark morph Broadwing Hawk all by himself, and not long after we
had an intermediate morph Swainson's Hawk.

Our Peregrines, and our other migrants, were flapping constantly fighting
that northern wind.

We had local red-tails, a Cooper's, two Turkey Vulture, an Osprey flying
south, and a local kestrel.

This local male Kestrel was my primary observer today he chased a lot of
other Kestrels out of town, he screamed at the Harrier flying past, but was
strangely quiet during the peregrines passing by. This kestrel also dove
under a bush as a probable sparrow flew out the other side.

Non-raptor Observations:
We had another Great Blue Heron migrate. For the second day in a row, the
highest bird I saw all day was a Great Blue Heron flying straight North
with no deviation.

Passerine birds were much more active today than the last couple of days as
well. I saw some Tree Swallows, a Rock Wren, Dark-eyed Juncos, Western
Meadowlarks, American Robins, Mountain Bluebirds, Black-billed Magpies,
Spotted Towhees, and probably others that I didn't write down.

Predictions:
Tomorrow looks like a warm and cloudless sky with winds from the East/
Southeast. I expect a surge of migrants who were unable to migrate during
the last 4-6 days of bad weather. Bring a neck pillow and fresh eyes
because I expect these migrants high and fast.
========================================================================
Report submitted by Official Counter (<j.f.peters58...>)
Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the top of the
ridge, turn left, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Subject: [cobirds] Re: Colorado Combined Yard List now on Google Sheets
An outstanding effort, Thomas, and also Bryan. What a fun and interesting
