Birdcast is currently (9:30pm) detecting over 300,000 birds in flight over the county. Migration generally doesn’t peak until around midnight, so this is shaping up to be by far the largest migrant push of the season. Get out and bird tomorrow morning if you can!

Ozzie re-found the MacGillivray’s in the planted area between the museum
and the St. Ignatius fountain. It was chipping in the bushes, and then it
moved to the roses, where we saw it.

Hi Melissa,
I was studying Western Bluebird and Mountain Bluebird specimens this
evening, and I'm feeling confident about this being a Mountain Bluebird.
What I noticed with the specimens is that the primaries in Western
Bluebirds end much closer to the tail than in Mountain Bluebirds. We expect
to see more tail extending beyond the primaries in Mountain Bluebirds than
in Western Bluebirds for both males and females.
Your photo perfectly captures the primary length in relation to the tail
length making this a clear identification. When looking for comparison
photos, I noticed there are some misleading photos where the bird's wings
are crossed over each other significantly, making the primaries appear much
shorter than the tail <https://macaulaylibrary.org/asset/622938047> or the
bird's tail is pressed down, making comparison between the primaries and
the tail challenging <https://macaulaylibrary.org/asset/216190731>. I made
sure to choose comparison photos where the wings and tails are touching and
aligned. Next time I'll be sure to take photos of the specimens because the
difference is unmistakable when both birds are forced into the same
position. Anyway, thanks for sharing the sighting!
Sincerely,
John

Took a trip up to Smith Creek on Sunday (with Eve Meier and Melanie Barnett) and saw a possible Mountain Bluebird there. She caught my eye for being exceptionally pale gray with no rust on the chest and a white vent. After checking with some local folks and on-line, most felt it looked good for a female MOBL, citing the shape, long-primaries, lack of yellow on the bill in addition to the overall gray & pale blue color. I've posted it to eBird on the checklist with notes, but if someone out in SBB-land is really familiar with them, please chime in!

This morning I birded Thompson Creek hoping for a Solitary Sandpiper but
was pleased with a SPOTTED SANDPIPER. The creek habitat was good for
migrants and deserves some attention. Hundreds of swallows foraged over
the creek, especially around Tully where they nest under the bridge.
I saw no swallows at Lake Cunningham which appears essentially dead.
Only a few ducks and gull were seen, no pelicans and only one GREEN
HERON. Some BUFFLEHEAD were in a small cove with a few egrets and
herons. The GREAT TAILED GRACKLES didn't seem to mind and were nesting
in cattails. The flooded fields have been drained and only a few CANADA
GEESE were lingering.
The native plant garden was quiet but I had one each WESTERN TANAGER,
BLACK HEADED GROSBEAK plus a small flock of CEDAR WAXWINGS here. I had
one HOODED ORIOLE here and two elsewhere.
I found a BLACK PHOEBE feeding nestlings in a Cliff Swallow nest under
the bridge. see photo
The good news was all the YELLOW WARBLERS seen or heard in the creek's
willows behind the water park. I heard five singing males and saw one
pair. A YELLOW RUMPED WARBLER remained, one PURPLE FINCH sang and a
HAIRY WOODPECKER was seen.
The only WESTERN FLYCATCHER for the day was heard as I was waiting for a
green light at Meridian and Coleman.
I heard both BLACK HEADED GROSBEAK and WESTERN TANAGER from my yard this
morning, so the migrants are slowly trickling in. According to Birdcast,
the next three nights show high migration for our area.

The Least Bittern was continuing today. Got beautiful bino views (and
blurry obstructed pics) of it flying right in front of me at the gap in the
reeds on the small trail East of the dock, then it disappeared into the
reeds just to the right.
It was overall an excellent day of birding at Calero Reservoir, including
an adult Bald Eagle being mobbed by basically everything, an Osprey
catching fish (that I finally managed to catch in good focus), a couple
Yellow Warblers singing in the trees near the dock, a breeding male Common
Merganser flyby, a couple of Grackles that walked right up to me, and the
usual suspects.
The Least Bittern photos are disappointing in every way other than
*existing at all* ;-).

It was a beautiful morning of birding today at Ed Levin County Park, Spring Valley Area. We set out with a group of intrepid birders with Liz Frith, John Tsortos, and Karen Rush coleading. Spring was in the air in Spring Valley as various birds carried food back to their nests. Western Bluebirds, Tree Swallows, and European Starlings were all seen carrying meals back to their nest cavities and bird boxes. The morning sky was full of raptors enjoyed the beautiful weather, including at least 3 Red-shouldered Hawks, 4 Red-tailed Hawks, 2 White-tailed Kites, a Golden Eagle, and a Cooper's Hawk.
We searched the eucalyptus trees and found a migrating male Rufous Hummingbird and both Bullock's and Hooded Orioles. The flock of 8 Lawrence's Goldfinches was also flying around the park. We got good looks at them both near the entrance of the park as well as up on the Spring Valley Trail. Overall, the morning was very birdy with 56 species on our checklist ( https://ebird.org/checklist/S233136667 ).

Like a lot of birders, I was stuck in a line of cars at the entrance to Ed Levin today while the ranger prioritized the vehicles entering for the fishing event that was happening today. Once I got in I parked near the dog run (the only parking still available) and walked across the lawn toward the Calera Creek Trailhead (on the northwest corner of the lake).
A one mile hike to the location of the Blue Grosbeak was very productive. In addition to the target bird (a male), I also came across many Grasshopper Sparrows, Lark Sparrows, Lawrence’s Goldfinches, a single Say’s Phoebe and more Lazuli Buntings than I could count. It was very birdy trail!
This was an unfamiliar trail to me, so I was happy to have some guidance from Chris Overington who was ilnformed me of the last location the bird 37.4646518, -121.8753461
The weedy basin located at these coordinates is beside the trail and immediately across a small muddy creek. When I arrived, a large group of birders was already on the bird which was perched on the wires over the fennel patch. I saw it return to the wires a couple of times, but I never saw the female the other group had seen briefly.

Date: 5/4/25 2:37 pm From: Matthew Dodder via groups.io <mdodder...> Subject: [southbaybirds] Team Subspecies — full report 05-03-25
Yesterday, my fourth and final Birdathon team ventured out on its 4-hour effort. The Subspecies consisted of Andrew Melnick, Liz Frith, Jim Dehnert, Christopher Klein, Kelly and Matthew Dodder. Ally Romanow and Sue Pelmulder had intended to be with us but last minute conflicts that prevented them from joining the birding portion. Many others supported our team (and SCVBA) through their sponsorships, and for that we are grateful!
The team was faced with cool and drizzly weather—a far cry from the brilliant day before or the sunny warmth of today. But we did not let this get us down. We still found many of our targets but had some embarrassing misses on our trip list.
We began at the Stile Ranch trailhead leading up to Santa Teresa County Park. Our targets were obvious, Rufous-crowned Sparrow, Lark Sparrow, Grasshopper Sparrow, and Horned Lark. We managed to find all of them despite the drizzle, but we were never actually able to view the Grasshopper Sparrows. We had a tiny and intriguing Hummingbird zip past us on the switchback portion of the trail, and while we were tempted to call it a Calliope Hummingbird, we lacked enough evidence to add it to our list.
After returning to the gravel lot, we headed toward Harry Road along the Calero Creek Trail. We continued to hear Rufous-crowned Sparrows, Lazuli Buntings and Wrentit the entire length of the trail until we crossed the dry creek and passed through the orchard section. There we added Ash-throated Flycatcher and a single Wood Duck flying high overhead. When we reached the wooded creek section, we added Warbling Vireo, Orange-crowned Warbler, Song Sparrow and other expected species. Oddly, we had no Western Flycatchers here or anywhere the entire day. But we did get our first-of-season Swainson’s Thrush. Heading back to the cars we added Blue-gray Flycatcher and White-throated Swift.
Our final stop was at the Calero Reservoir boat launch. We quickly added a number of waterbirds including Western Grebe, Clark’s Grebe, and Pied-billed Grebe. We were also treated to views of two different Bald Eagles (one adult, and one immature), White-tailed Kite, and Yellow Warbler. Our biggest surprise was when we walked the trail along the north edge of the lake leading from the boat ramp toward the east end. Our group was slightly stretched out, but not so much that they missed my repeated scream “LEAST BITTERN! LEAST BITTERN!! LEAST BITTERN!!!” Everyone got a look at the bird as it lifted out of the reeds and took off toward the east end of the reeds. From my observation, it struck me as a male—a small dark-winged bittern with golden coverts and a very dark back with white streaks and greenish legs. Everyone echoed the observations and we were pretty confident this was the best bird of the day. After scanning the shore and not finding the bird again, we returned to the parking area taking a slightly different route—picking up a tick or two… I was in front of the group when I heard the folks behind me yell out BITTERN as it flew up and east along the water. This “second" bird was farther west than the initial bird and made us consider the possibility that it was actually two individuals. Something to look for. It would be wonderful to have them breeding in the county again!
We ended the day with 86 species (pending final checklist review)
As far as embarrassing misses. Rock Pigeon, American Robin, Western Flycatcher and probably a bunch more…. Oh well.
Thank you to all my teammates and to our sponsors.

Thanks Carter!
Gaurav just re-found the Olive-sided Flycatcher where you reported it! (Thanks Gaurav!) The bird is perching in a newly leafing-out very tall tree with lots of bare branches on top.
I have been looking for OSFL during migration since my return to California two years ago! Thanks for the heads-up; it was really nice to see one just a mile from my house!

Today 5/3/25 at 5PM. I made another attempt for the continuing county rarity. (Thanks to everyone who responded to my earlier query about this bird). But today there were 2 BLACK OYSTERCATCHERs, easily seen from the maintenance road, on the left (north/west) end of the island on Shoreline Lake, near the "Sensitive Habitat" sign. At one point as the two birds faced each other, one of the birds started calling loudly and it felt like a display. I quickly decided to try and digiscope them and luckily I managed to get the phone camera and scope aligned just in time to get a shot of the birds copulating! One of the birds briefly mounted the other in apparent copulation. I waited 40 minutes but they did not repeat this. More than once they and the ~35 BLACK SKIMMERs, BLACK-NECKED STILTs, and AMERiCAN AVOCETS would flush, fly around the island and then settle back in the same location.

Date: 5/3/25 7:52 pm From: Ryan L. via groups.io <ryanbirding...> Subject: [southbaybirds] Ed Levin CP 5/3/25
Since the weather looked like it would stay cool, I decided to try some new trails at Ed Levin. Even though I arrived at 8:30am the “Fish Day,” the parking lots at Sandy Wool Lake were full, and people were directed to park on the grass.
I followed Mountain Peak Road up the hill. The yellow mustard fields were full of Red-winged Blackbirds. Up the hill, I found a Rufous-crowned Sparrow and Say’s Phoebe and heard a Grasshopper Sparrow. At the top, I followed the South Branch Calera Creek. I saw Bullock’s Oriole, Northern House Wren, Lark Sparrow, and a flock of Cedar Waxwings.
I arrived at the creek, and there were three other birders looking for the Blue Grosbeaks. (37.46535° N, 121.87635° W) The male and female flew towards us but stayed in the mustard. In the same area were Lazuli Bunting, Lark Sparrow, Lawrence’s Goldfinch, and Western Bluebirds. (All the blue birds today!) Along the creek, I saw or heard Black-headed Grosbeak, Ash-throated Flycatcher, and I got a really good view of an Olive-sided Flycatcher perched on a branch.
On the way back to the parking lot, in the golf course, was a Great Blue Heron and Great-tailed Grackles. (It must be a great course.) While driving out, I scanned the lake and saw most Double-Crested Cormorants.
I stopped briefly at the Spring Valley side and saw Western Kingbird, White-tailed Kite, Cooper’s Hawk, and a Black-crowned Night Heron.

Date: 5/3/25 4:41 pm From: Lisa Myers via groups.io <lisa...> Subject: [southbaybirds] Vasona County Park - Los Gatos
Hi all -
I led a walk at Vasona County Park this morning. The park was humming
with people as there was a "Walk MS" event today with loads of people,
dogs, music and food. (Makes me wonder why birder's don't organize a
walk with hundreds of birder's gathering together to walk a park spread
the word about nature.)
Other than the music playing in the distance - Neil Diamond, KC and the
Sunshine Band etc.,the bird song was rather quiet. We started off
University and soon found *WESTERN BLUEBIRDS* taking food into their
nest cavities. *AMERICAN ROBINS* were also amongst the trees and a
*RED-SHOULDERED HAWK* got the American Crows all stirred up. As we
walked down the road toward the lake we found the *GREAT-HORNED OWLS
*that frequent the Eucalyptus trees. We found an adult on the south side
of the road and two fuzzy young sitting together on the north side of
the road. The question was asked how old until a young owl can fly?
Young birds will often hang out on the ground and can get themselves
back up a tree without actually flying, but the experts say the owlets
will start to fly around 9 - 10 weeks of age. The great news is that the
owls are still using this area of the park even though many of the huge
Eucalyptus trees were removed last fall.
As we walked down to the lake on this overcast damp morning the swallows
and swifts were all around. *VUAX's SWIFT* flew over on several occasion
and we observed *WHITE-THROATED SWIFTS* higher up. *NORTHERN
ROUGH-WINGED SWALLOWS*, *BARN SWALLOWS* and *VIOLET-GREEN* were
numerous. While standing on the red bridge we had great views of all the
swallows species flying below us. Super way to learn their field marks
and vocalizations.
Once across the bridge the CANADA GEESE with goslings were abundant.
*BROWN-HEADED COWBIRDS* kept calling and one *HOODED ORIOLE* was spotted
near the boat ramp.

Date: 5/3/25 3:55 pm From: Matthew Dodder via groups.io <mdodder...> Subject: [southbaybirds] DeDUCKtions full report (4-26-25)
Last Saturday I led my DeDUCKtions Birdathon team on a whirlwind tour from the East Hills to the Bay and then finally to the West Hills. This cross section of the county was fast paced and efficient compared to some of our previous routes, giving us access to a variety of habitats with fairly, short intervals of driving. Participants were Matthew Dodder, Kelly Dodder, Eric Goodill, Mary Ann Allan, Brooke Miller, Ashutosh Sinha, Ellyn Corey, and Ally Romanow.
We began at Spring Valley (Ed Levin) at 8:00 searching first for any Selasphorus Hummingbirds or Orioles at the large eucalyptus tree by the corral. We only heard one Selasphorus and it never appeared long enough for us to identify it, and found a pair of Bullock’s Orioles. We had good luck with the Lawrence’s Goldfinches, but the Phaiinopepla has been absent for about two weeks now and so didn’t appear for us. A pair of Golden Eagles appeared over the ridge and one White-tailed Kite was hovering above the trees by the lake. Early on our visit, Eric spotted an Osprey flying away from the lake.
At Sandy Wool (Ed Levin) we continued to hear Lawrence’s Goldfinches near the hang glider landing area as well as Lark Sparrow. Our real target was the Grasshopper Sparrow along the steep trail to Agua Caliente. Luckily we found it long before the steepest part of the trail. We also had our season first Lazuli Bunting here. Obviously, the lake presented a few water birds like Black-crowned Night Heron for us as well as Great-tailed Grackle.
After leaving this area, we drove to Don Edwards and birded the entrance road to the Environmental Education Center (EEC). There we found a treasure trove of new birds for our list including Semipalmated Plover and breeding-plumaged Dunlin. At the native garden beside the facility we scoped the ponds finding a few new species such as Forster’s Tern, Western Grebe and Canvasback.
From there we made a quick stop at Sunnyvale Water Pollution Control Ponds just long enough to add Caspian Tern, and our target Green Heron and Common Gallinule. Marsh Wren was easy to hear at this location as well, but since we had already found them at Don Edwards we were more excited by the House Sparrows that were hanging out along the channel.
A quick stop at the Kite Flying are of Shoreline Park provided distant views of Burrowing Owl, but we also found Western Kingbirds and a lingering Merlin that landed on a power tower above the kiosk—a spot I’ve often seen this species perch.
We birded both the clubhouse area and the Terminal Blvd section of Shoreline Lake. The Black Skimmers, Black Oystercatcher and Lesser Yellowlegs were all found but we did not locate the female Common Goldeneye. I wish we had had time to look at A1 more thoroughly, but we were getting quite tired by late afternoon and still had three stops to go.
Pichetti Ranch OSP was not very birdy, perhaps because of the cool temperatures and the slight drizzle we encountered. This didn’t seem to discourage the revelers at the picnic tables… In fact, much of the day was less active as far as birds than we had hoped, but we still managed to pick up a bird or three, namely Wild Turkey, Orange-crowned Warbler and Black-throated Gray Warbler.
At the nearby Lake View Picnic Area overlooking the Stevens Creek Reservoir we were not optimistic about finding our target since the water was so high and litter exposed shoreline was available. A careful scanning of the entire lake however gave us what we came for a Spotted Sandpiper!
Finally, just before our clock ran out, we caravanned to McClellan Ranch where our Black-chinned Hummingbird female, the bird that I had reported just a day earlier, put in a brief appearance at the feeder before streaking off again. Sadly, two birds we missed on our 10-hour effort eluded us completely. Today however, when I arrived at work and opened my car door the two birds mocked me with their familiar calls. Both Brown Creeper and Western Flycatcher just wanted to rub it in…
We ended up with 124 species, which was eleven more birds than last year. Mission accomplished!

I stopped by a small neighborhood park on Guadalupe Mines Road not
expecting much since they severely trimmed the oaks. Much to my surprise
I looked up into a tall oak and spotted a YELLOW BREASTED CHAT staring
down at me. It disappeared before I could untangle my eyeglasses string
from my hat string and get a photo. It looked huge with that big bright
yellow breast. I noted the dark head and white spectacles before I lost
it. I waited around a while, then left to bird nearby Guadalupe Creek. I
soon returned but the chat was still silent and not found. I believe the
nearby fountain is what attracted it to the neighborhood. see photo
The park is called Via Fortuna just past the entrance to Via Campagna.
It's not a suitable habitat for the chat, so I expect it will soon leave.

Hi Everyone!
This morning Subha Mohan, Amanda Newlove and I led a "slow birding" trip to Coyote Valley Open Space Authority. This trip was designed for people who need or prefer a slow paced, shorter trip. We birded from the picnic tables in the parking lot and the picnic tables under the large oaks in the meadow. Our favorite birds of the morning were a *Western Tanager*, the *Yellow-billed Magpies* and the *Western Kingbirds*. After the trip while a few of us remained, we saw a *Red-winged Blackbird* pretty much riding the back of a *Raven* in his attempts to scare the Raven away. We wished we had had a camera!

Thank you for being a member of South Bay Birds [SBB]. This is our monthly reminder sent to the list with information about the group.
South Bay Birds [SBB] is a list intended for reporting the interesting birds you find in Santa Clara county, in order to help your fellow birders see them as well. We encourage everyone to share where they bird and what they see. Please include the general location (e.g., an eBird hotspot) and, if appropriate, the bird(s) of interest in the subject line, with any additional detail needed in the message body. If you use eBird, we encourage you to include a link to the eBird trip report that you filed.
This list is maintained by the Santa Clara Valley Bird Alliance ( scvbirdalliance.org) ( https://scvbirdalliance.org ). Their volunteers and funding keep the list running so please consider joining or donating to them. SBB's Lead Admin is Jim Dehnert. Chuq Von Rospach, Brooke Miller, Matthew Dodder and Barry Langdon-Lassagne assist Jim. You can contact the administration team with your questions and concerns at southbaybirds+<owner...>
The home site for this list is https://scvbirdalliance.org/siliconvalleybirding and you can find out more about us there. To start sending messages to members of this group, send email to <southbaybirds...>
The birds we watch should be our primary concern. As birders we need to be sensitive to their needs and not do things that put the birds or their habitat at risk.
We believe all birders should act as ethical birders. Your personal year list or that special photograph could put the bird at risk or cause its nest to fail. Because we expect all birders to act ethically around the birds that bring them joy, we expect that of the birders who are on our list as well. We have written up some ideas of what it means to be an ethical birder, and list links to other resources on ethical birding as well. Please read them and act to put the bird’s needs ahead of your own. If we find out that members of the list are putting birds or their habitat at risk, those members may lose access to the mailing list and its resources.
We also believe that members of the list should treat each other properly. If a list member is found to be attacking or harassing other list members, or engaging in activities that violate the ethical birding code it may affect their future ability to contribute to or subscribe to our lists.
*Acceptable Content*
The primary content for SBB is reports of interesting birds you saw and where you saw them ( https://groups.io/g/southbaybirds/message/24065 ). The objective ( https://groups.io/g/southbaybirds/message/25078 ) is to help other birders interested in the birds you saw to find them themselves. Please include the general location (e.g., an eBird hotspot) and, if appropriate, the bird(s) of interest in the subject line, with any additional detail needed in the message body. Please report only Santa Clara County locations -- other counties have their own mailing lists for trip reports.
Occasionally the administrator will post an Advocacy digest -- no more than once a week, and more typically much less often. This digest contains topics that are not typically posted to the list but we feel are of interest to the readers of SBB and are important enough to warrant posting to the wider audience. These messages will be tagged with the word "Advocacy" in the subject so members who aren't interested can delete or filter them if they choose. Topics posted as Advocacy messages typically include updates on important Advocacy activities by Santa Clara Valley Bird Alliance (SCVBA) and SCVBA volunteer activities.
*Unacceptable Content*
Do not disclose information that identifies the location of nesting birds of any species, to minimize stress on the nesting birds and the risk of vandalism or abuse.
We discourage general discussion and questions on South Bay Birds, for that we've created a Facebook group (see below). If you wish to propose a general-purpose announcement for an Advocacy digest post, please send the proposed text to the administrator (below).
Please do not post notices of upcoming events to SBB. There is a sister list, South Bay Birds (Events) [SBB-Events], that should be used for that purpose. If you are interested in knowing what events are being offered by SCVBA and other county bird-oriented organizations, we encourage you to subscribe to this list (see below).
Please do not post carpooling requests for events to SBB. We request that they go to the Facebook discussion group.
*Unsubscribing from South Bay Birds*
If you ever need to unsubscribe from this list, an unsubscribe link is at the bottom of every message, or you can go to https://groups.io/g/southbaybirds/. That's also where you can view the list archives, set up a vacation hold, change your email address, or modify your subscription in any way.

I was the Sunnyvale sighting! Glad to see that I’m not alone anymore :)
Just a heads up, a reviewer actually reached out to me in mid-April (my sighting was Feb 25) with the feedback that my footage was not sufficient to assert the species level, and I was instructed to revise it to “Zosterops sp.”. My overall memory of the bird was a reasonably confident Swinhoe’s due to the high level of contrast between the green-olive back and various lemon-yellow parts, but of course it would be great if someone could gather conclusive evidence.

Hi SBB'ers, I went up to Stevens Creek County Park to look for the Nashville's Warbler reported there (no luck), but was informed that the Tony Look trail was obstructed by a massive fallen oak -- after the trail takes a left at the lake. I went up and took a look. The oak is approximately here 37.293698, -122.073183 up the trail from the NAWA coordinates, just past where the MGWA was reported last year. A person could crawl under if you don't mind that it was wrapped in poison oak or are and might shift and crush you. The ranger told me crews would be dispatched in the next day or so, which may cause a trail closure and noise. The trail up to the dam and the Loop trail are unaffected. Be safe out there!

This morning I heard both song and calls of what sounded like a Northern Waterthrush along the section of Los Gatos Creek Trail north of Lark Ave. I did not see the bird. I did get not-so-great audio recordings. The song—two series of repeated notes, maybe with a single final note sometimes—was a bit deeper than most warblers’. The call was a fairly powerful chip, not really like any of our common birds.
This was in the vicinity of the first parking lot on Charter Oaks Dr (37.25353° N, 121.96336° W). I last heard it singing along the creek at 9:23 am slightly south of the parking lot. The creek itself is far from the trail here and not visible, but the bird actually sometimes called from the inland side of the trail.
I also heard a Black-chinned Hummingbird and a Western Tanager from this spot.

Today I led quite a team of folks for the Santa Clara Valley Bird
Alliance spring birdathon. We had a vast array of skill levels which
helped in gathering our species. This year I decided to mix it up by
going out on a Sunday evening with the goal to find owls and poorwills.
We started at Rancho San Vicente Open Space Preserve at 4:30 PM. Our
entire 4 hours was under dim, overcast conditions. Starting late in the
day meant sacrificing the dawn chorus, but the bugs were here and so
were the swallows including CLIFF, VIOLET-GREEN at BARN. We started our
afternoon with a pair of LAWRENCE'S GOLDFINCH just off the parking lot
near the picnic table north of the bathrooms. Once on the trail three
WESTERN KINGBIRDS were rather cooperative. After listening to the
WESTERN MEADOWLARK we finally observed just one on the fence.
A pair of LARK SPARROWS were easy to enjoy as they hung out on the trail
in front of us. A distant GOLDEN EAGLE was being harassed by an AMERICAN
CROW. And a WHITE-TAILED KITE was hunting.
From there we drove over to the Harry Road entrance to the Calero-Creek
Trail. We started with a RED-SHOULDERED HAWK sitting on a phone pole as
we all parked. We first birded the area around the IBM entrance and
found ASH-THROATED FLYCATCHERS, SPOTTED TOWHEES, NUTTALL'S WOODPECKER,
BLACK PHOEBE, RED-TAIL HAWK, WHITE-BREATED NUTHATCH and STARLINGS. All
in all the birds were quiet and we missed species that have been
reported lately, but our goal was to find owls and poorwills. As we
walked south down the trail we had WOOD DUCKS fly over. We also found
one male LAWRENCE'S GOLDFINCH on the top of an orchard tree. We also
picked-up the distant hoot of a GREAT-HORNED OWL. That was the best we
could do for that species.
Once across Santa Teresa Creek we found deer, CALIFORNIA QUAIL, calling
WRENTITS and a RUFOUS-CROWNED SPARROW. ASH-THROATED FLYCATCHERS and a
WESTERN KINGBIRD were out too. We were now birding under low light and
having a nice pair of binoculars comes in handy under such conditions. A
found a pair of AMERICAN KESTRELS and eventually had heard only LAZULI
BUNTING. (Jack rabbits come out at this time too.)
With the sun down we headed back and just after crossing Santa Teresa
Creek we stopped to listen for anything and BINGO the COMMON POORWILL
started to call (hallelujah). The call got louder and then we heard a
2nd poorwill calling from a distance down the trail where we had just
been. After several minutes it got quiet. So we continued and soon saw a
BARN OWL silently fly past the team. We could follow it and observed it
hunting low over the field south/west of the area where the trail
crosses Santa Teresa Creek. Later we heard the typical Barn Owl "scream".
What a great way to end our birdathon. Mission accomplished.
I thank all that were on the team and those supporting our efforts.

Hello everyone,
This morning, the same party from last month (myself, Olive L, and our
canine companion) observed another Ruddy Turnstone at the end of the
boardwalk at Palo Alto Baylands. Last month, the turnstone we observed was
on a rock that was determined to be in Santa Mateo County. This morning's
bird was situated on debris that is substantially closer than the rock from
our previous observation, making us fairly confident that the bird from
this morning was in Santa Clara County. Information about the specific
debris from our observation as well as the timing with the tides can be
found in our checklist for anyone interested in chasing this bird (a scope
is essential): https://ebird.org/checklist/S229752666
We didn't have time to triangulate the location of this debris, but if
anyone does, I'd be happy to hear what you find.

Hi Everyone!
This morning I checked out Rancho Cañada del Oro. It was very quiet but I did see a pair of Lawrence’s Goldfinches in the first big meadow at the start of the Longwall Canyon Trail. After this location, I drove to the end of Oak Glen Ave. Songbirds were mostly silent but there were Caspian and Forster’s Terns, a female Wood Duck with about 8 recently fledge young, an American Avocet, two Semiplamated Sandpipers and 15 or so Western Sandpipers. I thought that was unusual and made up for the quiet day at Rancho Cañada.

I did not see the White-throated Sparrow yet today, but yesterday it was obvious near the feeder. I hope it sticks around until tomorrow when my DeDUCKtions team sets out on its Birdathon day.
Today I heard a stinging Western Tanager outside my office door and quickly grabbed my binoculars. It was high in the thick old trees beside the building and resisted my efforts to get a look.
I’ve also been waiting for the Black-chinned Hummingbird to arrive at McClellan Ranch, and today was the day I spotted a female at the flowering salvia beside the feeders. She showed a clean whitish throat, small rounded head and slender neck, paddle-shaped wingtips, and long bill. She explored the flowers and also visited the feeder a couple of times. So far only one individual as far as I could tell, so I hope a male shows up soon. I will keep watching the native plantings of salvia and monkey flower across from our building.
Earlier this week I heard the Bullock’s Oriole again, and even caught a glimpse of it as it flew across the meadow. They always seem less common than the Hooded Orioles at this location.
At least three Western Flycatchers, as many as six Warbling Vireos. A couple of Orange-crowned Warblers, and a Wilson’s Warbler were also vocalizing along the creek trail and near the Alpaca enclosure. Two pairs of Northern Rough-winged Swallows are focusing their attention on the bridge leading toward the overflow lot.

Today, I led my very first trip for Santa Clara Valley Bird Alliance and
chose to do it on my "patch," the Penitencia Creek Trail where I bird at
least 2 to 3 times a week. I was blessed to have a warm, wonderful group of
people and very grateful to my co-leader Melanie Barnett who is just
outstanding. Although the weather was cold and cloudy, we were not
disappointed by what we were able to find. We found 42 species plus some
hybrids and a Muscovy Duck. The highlight for everyone were the rufous
hummingbirds busily feeding on Pride of Madera. We also got great looks at a
western flycatcher, Steller's jay, and northern rough-winged swallows (like
7 of them all lined up on a low bare branch for us.) We actually had 4
different species of swallows. Besides the NRWS, we also had barn, tree and
violet-green swallows but they were mostly moving too fast and too high to
get good pictures or even clear counts or IDs. We also had a lone ruddy
duck, a belted kingfisher, both ACORN and NUTTALL'S WOODPECKERS, a COOPER'S
AND A RED-SHOULDERED HAWKS, a BULLOCK'S ORIOLE. It was a great experience
and I am so grateful to SCVBA for all the wonderful opportunities they've
given me to learn and grow as a birder. Please consider supporting the
ongoing Birdathon that helps encourage young birders from local low income
schools.

Hi Everyone!
Today a small group of us birded Debell Uvas Creek Preserve to get ready for next week's SCVBA field trip to that location. I think it was a little bird quiet for that location, perhaps due to the cold weather. But, we did spot 4 *Hooded Orioles*, 2 *Lawrence's Goldfinches*, 3 pairs of *California Thrashers*, and a large flock of *American Goldfinches*. Several *Black-headed Grosbeak* were singing and we were finally able to get our eyes on one of them.
After that location, I went across the street to eat my lunch at Christmas Hill Park. I spent most of the time on the large lawn right next to the creek. Here I had *Bullock's Orioles*, a male *Western Tanager*, a pair of *Lawrence's Goldfinches* (perhaps the same pair), a *Bald Eagle* and a *White-tailed Kite*.

The Wrong Terns went out for a morning of birding today to McClellan Ranch, Blackberry Farm, and Linda Vista Park. Highlights of the event included seeing a territorial dispute between a pair of adult and juvenile HOODED ORIOLES at Blackberry Farm, nesting PYGMY NUTHATCHES, MALLARD ducklings in Stevens Creek, and a WHITE-TAILED KITE soaring high above the preserve. We ended the day with lunch at the McClellan feeders, and 42 species for our 4 hours of birding.
You can support the Wrong Terns' fundraising efforts here: https://scvas.app.neoncrm.com/np/clients/scvas/campaignTeam.jsp?campaignId=194&teamId=142&. Funds raised in the SCVBA Birdathon go to fund our education programs in Santa Clara County, allowing us to offer our programming for free to low-income schools, cover material costs for programs like owl pellet dissections, and offer schools bus funding support (bus funding is the biggest hurdle preventing schools from providing field trips to students).
I also wanted to take a moment to thank all of the amazing birders who have already or will be taking part in Birdathon this year! You've had some amazing finds with your teams, and together we've raised a really impressive total for SCVBA's education programs.
Have a great day, and happy birding,

I birded the one mile loop trail at Shannon Valley OSP this morning.
Starting at the trailhead at the west end of Mountain Laurel Lane my
only BLACK HEADED GROSBEAK was heard. Climbing the switchback I heard a
HOUSE WREN and saw two LAZULI BUNTINGS. Another bunting sang near the
top of the hill where I also had BLUE GRAY GNATCATCHER'S and an ASH
THROATED FLYCATCHER.
The WHITE TAILED KITES have relocated from the ridge to the south side
of the trail. Along the open trail through the grass were three heard
only LAZULI BUNTINGS singing from the hillside. Further east I saw two
more buntings closer to the trail but failed to get a photo.Swallows and
Swifts soared overhead.
The trail along Hicks was difficult to bird due to tree trimming. I
heard two more ASH THROATED FLYCATCHERS another HOUSE WREN and a single
WARBLING VIREO from the paved trail. DOWNY WOODPECKERS and HOODED
ORIOLES were near Shannon Road. CAL. QUAIL pair were seen in many
locations but Cal. Thrashers were quiet today.

Yesterday, my intrepid Birdathon team of Eve, Liz, Jackie, and I ranged hither, thither and yon to find as many species as possible all day. I had a personal best day in: checklists (12), species(116) and distance walked while birding (>10 miles).
My birding lesson of the day (aside from how amazing my team is, of course): I hadn't realized breeding Dunlin can have black bellies. That puzzled me for some time.
When the whole tale was told, the Rangers found 140 species. With my promised Sawbuck-per-species and other donations from the team, we raised $1580 for the SCVBA's Education Program.
While truly recounting my team's odyssey would require Epic Greek Poetry, I will highlight a few finds from each of the locations scouted, without repeating species :-):
Metcalf and Las Animas Roads: Western Screech Owl and about 30 California Quails (standing in the road, of course). Heintz Open Space: Purple Finch and California Thrasher. Laguna Ave: American Goldfinch and 5 Great Egrets. Shannon Valley OSP: Hooded Oriole and Northern House Wren. Dr. Gross ponds: Bullock's Oriole and Brewer's Blackbird. Coyote Valley OSP: Yellow-billed Magpie and American Kestrel. Los Alamitos Creek Trail (Singer/McKean): Western Flycatcher and Band-tailed Pigeon. Sanborn CP (entrance): MacGillivray's Warbler (!!!) and Cassin's Vireo. Calero Reservoir: 29 Common Mergansers and a Virginia's Rail (HO, naturally). Santa Teresa CP (BGJ Ranch): American Barn Owl. Parkway Lakes: Golden Eagle and Gadwall. Santa Teresa (Stile entrance) was visited 3 times: Rufous-crowned Sparrow, Lazuli Bunting, Common Poorwill, and Great Horned Owl. Bear Creek Redwoods Pond: Northern Rough-winged Swallow and Pygmy Nuthatch. SCV Water District: Ring-necked Duck and Black-crowned Night Heron (they were scarce today, only 4 seen in all locations). Calero Creek Trail (Harry Rd): Say's Phoebe and Lawrence's Goldfinch (HO). Sanborn (John Nicholas): Pacific Wren and Black-headed Grosbeak. Shoreline kite flying area: Burrowing Owl and Savannah Sparrow Shoreline Park (lake); Lesser Yellowlegs and around 50(!) Black Skimmers. Sanborn (Lake Ranch Res): Wood duck and Pileated Woodpecker. Casey Forebay: Marsh Wren and a ton of Barn Swallows. One of the ranger's backyard: Vaux's Swift. PA Baylands: 9(!) Whimbrels at the boat launch and a huge number of Marbled Godwit in the distance. Sunnyvale Shopping Center: Mitred Parakeet. Emily Renzel: Common Gallinule and White-tailed Kite -- Ray

The Almaden Eagles team did our SCVBA Spring Birdathon on Friday, April 18. We are an all-women distributed team of eight participants in which each person takes her own part of the Almaden area and nearby vicinity to count. The start of our morning was under very cloudy overcast conditions which didn't begin to clear up until later in the day, not what we would have hoped or expected but we persevered anyway, and came up with a good collection of birds for the day.
Birds seen and heard besides our local residents included a few lingering wintering birds (crowned sparrows, Hermit Thrush) - newly arrived spring migrants (orioles, flycatchers, vireos, etc) - 7 duck species - 6 woodpecker species - 5 swallow species - 5 finch species - 11 sparrow-types - 5 warblers - and more.
Here I want to acknowledge our team members with some of their unique birds seen during the day
JANNA PAUSER: Hicks Rd & most of the New Almaden area - Pileated Woodpecker - and later, Great Horned Owl, W. Screech Owl, Common Poorwill AMANDA NEWLOVE: Mt Umunhum area & nearby vicinity - five warbler species including Black-throated Gray Warbler - Chipping Sparrow - 14 Band-tailed Pigeons KIRSTEN HOLMQUIST: portion of Stile Ranch Trail including Horned Lark, Rufous-crowned Sparrow & Lark Sparrow - Calero Reservoir: Wilson's Snipe, White-tailed Kite, Caspian & Forster's Terns, and "rushing" Western and Clark's Grebes MARION FARBER: Los Capitancillos Ponds - female Wood Duck with very young ducklings - Spotted Sandpiper (the only one for our day) BROOKE MILLER : Calero Creek Trail & nearby vicinity - Lawrence's Goldfinch, American Goldfinch, White-throated Sparrow, Lazuli Bunting (first one of season) BOBBIE BAKER: Los Alamitos Creek Trail from Mazzone to Camden bridge a male Black-chinned Hummingbird (first one of season seen in this location) - Common Mergansers LINDA SULLIVAN: Almaden Lake & Water District - Linda gave us our "eagle" for the day - a Bald Eagle seen in both locations - also detailed sightings of the heron/egret nesting island - Vaux's and White-throated Swifts ANN VERDI: portion of Guadalupe River Trail from Coleman Rd to the spillway - many N, Rough-winged Swallows seen around Coleman Rd where they nest underneath the Coleman Rd vehicle bridge - and 6 newly arrived Cliff Swallows beginning nesting activities under the Coleman pedestrian bridge - and then at least 5 House Sparrows in the bushes near the apartments (hey, they count too!)
We ended up with a total of 121 species for the day - the highest number for this all-women team. I want to thank all our team members for their efforts that day - especially during the gloomy overcast at the start of the day. Way to go, team!

Spent the day birding yesterday as part of the Rock Wrens distributed team. Started just before dawn at the John Nicholas trailhead. Was happy to hear three PACIFIC WRENS calling on the path out to Lake Ranch reservoir. Last year, I had only one calling. Still below historical numbers.
Just like last year, there were no Great Horned Owls calling. Would love to understand why they are so prevalent some years and seemingly absent others weather? food? luck?
Surprised and happy to have a pair of male WOOD DUCKS in the reservoir. First time I have ever seen them there. But I dipped on Pileated Woodpecker at John Nicholas for the first time (though Merlin thought one did a short call later at Sunnyvale Mountain Trailhead did not count it).
WESTERN TANAGER and CASSINS VIREO were present and calling at various points on the trail, but the Cassins numbers were down relative to previous years. Lots of WARBLING VIREOS and BLACK-HEADED GROSBEAKS.
Headed to Sunnyvale Mountain Trailhead. Not much about. Fewer YELLOW-RUMPED WARBLERS than in recent years. Had my one and only TOWNSENDS WARBLER of the day there. Did not have Black-throated Gray Warbler at all, which was surprising.
Both saddles at Loma Prieta were quiet. No Black-chinned Sparrows, no buntings, barely a hummingbird about. For the first time in quite a few years, I dipped on Olive-sided Flycatcher there. Normally reliable. Happy to hear RED-BREASTED NUTHATCH calling, and had my only ASH-THROATED FLYCATCHER of the day there. Merlin heard a Purple Martin, but I didnt (so not counted).
After noting last year that the CLIFF SWALLOW colony at Lexington Reservoir wasnt there, was happy to see it back this year.
Didnt bother to check downtown Los Gatos for the Dipper as it has not been reported at all, and has been tough in recent years.
CHIPPING SPARROW calling in Blossom Hill Park. No Lazuli Buntings at Shannon OSP, though I suspect there will be quite a few there soon (last year had many just a bit later). Did have 2 x NORTHERN HOUSE WRENS there.
Vasona had a GREEN HERON and a solitary full breeding plumage RUDDY DUCK. Also one solo GREAT-TAILED GRACKLE, which I had not noted there before.
Los Gatos Creek Trail / Oka Ponds was very quiet. No ducks. But did have SPOTTED SANDPIPER on an island in the creek.
Late day trip to McClellan Ranch, Stevens Creek Reservoir and Canyon and Redwood Gulch road failed to produce the hoped-for Orioles. Final add for the day was HUTTONS VIREO calling loudly next to the Stevens Creek Canyon Road.
Overall, only 58 species this year, down quite a bit from 87 last year (mostly due to different routing didnt head down to Calero, Bailey, Stiles Ranch).

OnSaturday, 19 Apr 2025, I participated in the SCVBA Birdathon, joined for mostof the day by Janet Hanson.
Westarted at Coyote Lake County Park, visiting the dam. Unfortunately, theweather was fairly brisk with a good amount of fog, though the ground levelviewing was passable. For the seventh time this year, the Canyon Wren that hadbeen reported at the dam, stood me up. We had to settle for a Rock Wreninstead. Ducks were rather scarce on the reservoir this day.
Wethen worked our way up Gilroy Hot Springs Road, traveling slowly with carwindows down to hear anything we could along the way. After turning around tohead back to Canada Road, we got the surprise of the day. Janet spotted an interesting-lookingbird over the car and we stopped and jumped out. We were astounded to see animmature CALIFORNIA CONDOR soaring with a TURKEY VULTURE. After a coupleminutes, it soared high enough to disappear into the fog. This was about a halfmile past the Hunting Hollow entrance to Henry Coe State Park.
Wethen headed up Canada Road and turned on to Jameison Road to look for grasslandbirds. At one point Janet spotted a group of LAWRENCE’S GOLDFINCHES in withsome LESSERS; a nice addition to the day list. Then it was off to San FelipeRoad.
Westopped in the parking lot for the fruit stand at the corner of San Felipe andHwy 152, scanning the skies for any sign of Swainson’s Hawk. Unfortunately,they didn’t seem to be flying this day. So, we went down to the eucalyptustrees to look for kingbirds. We sat there for some time hoping for a sight orsound of these birds. Finally, a CASSIN’S KINGBIRD called from the middleeucalyptus, saving us from an embarrassing miss. We left going south, insteadof back to the highway, and were rewarded with a kingbird lineup on the fenceat the south end of the vineyard. It was WESTERN, CASSIN’S, WESTERN givinggreat comparison views.
Weworked our way over to Bloomfield Ave, and at its intersection with FrazierLake Road, we lucked into a couple of SWAINSON’S HAWKS foraging over a fieldthere. This was another target bird and we were glad not to have missed it, afterleaving San Felipe Road without it.
Afterdropping Janet off, I headed back out to continue birding by myself. Afterchecking out Calero Reservoir, I headed up McKean Rd towards Chesbro Reservoirand was rewarded with an OSPREY heading down McKean in the opposite direction.On Old Oak Glen Ave, I found some WOOD DUCKS and a SPOTTED SANDPIPER on thefeeder creek into the reservoir.
Finally,at the end of the day, I sat at the Stile Ranch Trailhead into Santa TeresaCounty Park listening to a COMMON POORWILL calling up the hillside. My lastbird of the day was a BARN OWL coursing over this same hillside, giving me 85species for the day.

I have now tried for the Black Oystercatcher at Shoreline Lake four times and just can't find it. Questions for those who have seen it.
- Did you see it from the West side of the lake from the paved maintenance road or from the East side from the dirt patch that leads to the lawn and play structures.
- Is it on top of the island or by the water?
- Is a scope needed?
Sorry for these questions but this bird somehow keeps eluding me!

Yesterday, Cricket and I did some birding around Gilroy. First unloaded our bikes along Cañada Road to ride to the end of Jamieson Road. The morning was cool and slightly overcast but we had many spring birds including Western Kingbird, Bullock’s Oriole, Black-headed Grosbeak, and Western Flycatcher. Most exciting was a high count of at least 16 LAWRENCE’S GOLDFINCHES. We ran into Rick Herder who was doing a survey and he reported finding even more in the restricted area. In light of all the reports of this species from Ed Levin, Grant Park and elsewhere, it seems this is an especially good year for the bird.
We also stopped at Hunting Hollow and again unloaded the bikes to ride Gilroy Hot Springs Road to the bridge. We had Cassin’s Vireo, Orange-crowned and Wilson’s Warblers, as well as at last 6 BLACK-THROATED GRAY WARBLERS from about halfway to the bridge and at the bridge. We also found Common Mergansers in the creek below the road.
Hiking along Hunting Hollow Road (trail) we first heard and then saw a PILEATED WOODPECKER.

Hi all -
I camped (with non-birders) the last two nights at Coyote Lake-Harvey
Bear Ranch County Park. Here are just a few fun moments. What an
opportunity to hone in one's birding by ear skills. With everything
green and lush some of the birds were invisible, but their song gave
them away. PURPLE FINCH, BLACK-HEADED GROSBEAK, ORANGE-CROWNED WARBLER
and ASH-THROATED FLYCATCHER were throughout the Lake View Campground.
Regarding raptors, the TURKEY VULTURES were the most numerous fly overs,
but during my two days I also observed RED-TAILED HAWKS, RED-SHOULDERED
HAWKS, an adult GOLDEN EAGLE, a NORTHERN HARRIER, WHITE-TAILED KITES,
and both a SHARP-SHINNED & COOPER'S HAWK.
After dark and throughout the night GREAT-HORNED OWLS were heard
repeatedly. On Thursday morning a NORTHERN PYGMY OWL was calling before
dawn. One night BARN OWLS were flying directly over the campground as
they were "kleaking" overhead.
We could also hear the clacking of GREAT-BLUE HERON chicks somewhere in
a nest. The adults herons were observed repeatedly flying overhead.
WILD TURKEYS own the campground as males walked around the campsites
displaying, and the CALIFORNIA QUAIL were also near.
A few WHITE-CROWNED SPARROWS remain and the swallows were in high
numbers. VIOLET GREEN and TREE were the most numerous. Some looking for
nest cavities. WESTERN BLUEBIRDS were also observed nesting.

Hi all -
I camped (with non-birders) the last two nights at Coyote Lake-Harvey Bear Ranch County Park. Here are just a few fun moments. What an opportunity to hone in one's birding by ear skills. With everything green and lush some of the birds were invisible, but their song gave them away. PURPLE FINCH, BLACK-HEADED GROSBEAK, ORANGE-CROWNED WARBLER and ASH-THROATED FLYCATCHER were throughout the Lake View Campground. Regarding raptors, the TURKEY VULTURES were the most numerous fly overs, but during my two days I also observed RED-TAILED HAWKS, RED-SHOULDERED HAWKS, an adult GOLDEN EAGLE, a NORTHERN HARRIER, WHITE-TAILED KITES, and both a SHARP-SHINNED & COOPER'S HAWK.
After dark and throughout the night GREAT-HORNED OWLS were heard repeatedly. On Thursday morning a NORTHERN PYGMY OWL was calling before dawn. One night BARN OWLS were flying directly over the campground as they were "kleaking" overhead.
We could also hear the clacking of GREAT-BLUE HERON chicks somewhere in a nest. The adults herons were observed repeatedly flying overhead.
WILD TURKEYS own the campground as males walked around the campsites displaying, and the CALIFORNIA QUAIL were also near.
A few WHITE-CROWNED SPARROWS remain and the swallows were in high numbers. VIOLET GREEN and TREE were the most numerous. Some looking for nest cavities. WESTERN BLUEBIRDS were also observed nesting.
I never made it to the dam.
Both nights at roughly 8:50 PM we saw the line of Starlink Satelites pass overhead flying south bound at roughly 8:50 PM. (Freaked out a few neighboring campers.)

Had a nice outing scouting for my Birdathon team coming up on Sunday.
Starting from Harry Road, I was very pleased to find a Lawrence's Goldfinch not too far up the trail. Either they're more common this year, or maybe I'm just getting better at finding them :-).
Many of the usual suspects were around, including Wrentit, Blue-gray Gnatcatcher, some Meadowlarks, a kestrel, and lots of swallows, both Violet-green and Tree.
Up near the curve towards the Santa Teresa Stile entrance I heard the lovely tones of a Lark Sparrow and was rewarded with some nice close looks.
I was not able to find the reported Ash-throated Flycatcher, and the wood ducks were absent this morning. Also missing were any Lazuli Buntings, which I'd been hoping for.

Hi South Bay Birders:
In February I missed a ‘non-countable’ bird. It was a White-Eye species
(Zosterops sp) seen near the intersection of Fremont and Hollenbeck in
Sunnyvale on 2025-02-25 by Rohit Bose. It was originally reported as a
Swinhhoe's White-eye, but the photo was inconclusive.
In March we added 12 new countable birds, bringing the total to 230 at the
end of the month. The average for March is 13 new birds, and an average of
224 at the end of the month. We also added one new ‘non-countable’ bird in
March, a Red-whiskered Bulbul seen by Petra Kinsman on Osborne Ave in Santa
Clara on 2025-03-15. Thank you to everyone who birded, and took the time
to report birds either on SBB, eBird, or send emails directly to me.
Here are the birds that were found in March:
1. Glaucous Gull (4), 2025-03-06, found by Mike Rogers at Salt Pond A12
2. Grasshopper Sparrow (3), 2025-03-08, found by Eve Meier and Edward Rooks
at Diablo Foothills Preserve (closed to the general public)
3. American Bittern (4), 2025-03-08, seen by multiple observers (John
Scharpen, Ariel Potter, Kenneth Mamitsuka, Olive Lee, and Tim Hoo) at
Byxbee Park
4. Warbling Vireo (2), 2025-03-14, found by Carol Ann Krug Graves and David
Graves in Monte Sereno
5. Vermilion Flycatcher (6), 2025-03-15, found by Edward Rooks at Joseph D
Grant County Park
6. Western Flycatcher (1), 2025-03-20, found by Al McKay on South Market St
in San Jose
7. Cassin’s Kingbird (4), 2025-03-21, seen by Mike Rogers along San Felipe
Rd.
8. Swainson’s Hawk (4), 2025-03-21, found by Mike Rogers at an undisclosed
location
9. Wilson’s Warbler (1), 2025-03-22, seen by Kim Farrell at Agnews Historic
Park
10. Cassin’s Vireo (2), 2025-03-25, found by Brooke Miller along the John
Nicholas Trail at Sanborn County Park
11. Black-headed Grosbeak (2), 2025-03-26, found by Dorothy Johnson at Alum
Rock Park, and Matthew Dodder at McClellan Ranch Preserve
12. Vaux’s Swift (3), 2025-03-26, seen by Ann Verdi at the Coleman Rd Bridge
As a reminder, here is what each rarity code means:
**Rarity Codes:
1 = common, always seen in habitat in season.
2 = fairly common, usually in habitat in season, but missed sometimes.
3 = uncommon, always around, but sometimes you can't find.
4 = rare, occurs yearly in the county, but not always in same places.
5 = very rare, does not occur every year.
6 = casual or vagrant, generally fewer than 10 records.

Hi Everyone!
Today, I did a couple of short bird outings. The first was at Heintz Open Space (37.233044489128396, -121.9271865628507). I was hoping for a MacGilvary's Warbler but I think it's too early. I could hear lots of *Orange-crowned Warblers* and one *Wilson's Warbler* but not much else warbler wise. I did see two different *White-throated Sparrows *and several *Purple Finch* were singing. This was along the flat portion of the Vista Trail.
I also made a quick stop at the Calero Creek Trail starting at Harry Rd. I spotted the *Lawrence's** Goldfinch* (I think there might have been two) that Janna reported earlier. There was also a pair of *Wood Ducks* in the creek and two *Lark Sparrows *were on the trail. Lots of *Warbling Vireos* were singing and I heard my FOS *Ash-throated Flycatcher and Western Flycatcher.*

The Hot Spotters, the second of my four Birdathon teams this year, ventured out Saturday morning for a 4-hour, three destination tour. Team members included Carolyn Straub, Steve McHenry, Daniel Whol, Allison Morantz, Joan Loney, Amanda Newlove, Christopher Klein, Kelly “Cricket” Dodder, and myself. We also had a visiting birder from New York who tagged along for a while and got several lifers!
We began at Ed Levin’s Spring Valley section to search for continuing birds like the Phainopepla, Lawrence’s Goldfinch as well as expected birds like Chipping Sparrow, Golden Eagle, Rufous Hummingbird. We were quite happy to find our FOS Ash-throated Flycatcher and a continuing Says Phoebe. At least two Western Kingbirds were present near the picnic area and tons of Tree Swallows.
Next we stopped in briefly at the Dog Run in the Sandy Wool portion of Ed Levin. Among the new birds were a single Lark Sparrow, Great-tailed Grackle and at least 5 Grasshopper Sparrows that were low enough on the Agua Caliente hill trail to make it feasible for our limited time. No Lazuli Buntings or Rufous-crowned Sparrows were heard from our low listening post beside the dog run.
Finally, we drove 20 minutes or so to reach the Don Edwards EEC. There we were able to get a number of birds unlikely at the previous two stops. Namely, American Avocet, Black-necked Stilt, Semipalmated Plover, a single Snowy Plover, tons of Lesser Scaup, Canvasback, Ruddy Duck, and Western Grebes that we scoped in A18 from the corner of the Native Garden. As luck would have it, we also heard a Virginia Rail in the slough beside the entrance road.
We ended up with a very satisfactory 99 species but missed some obvious birds. Perhaps the Subspecies trip in a few weeks will correct that but they will be using a different route.
Thank you to everyone who pledged their support for our team. Your donations will go directly (and entirely) to our Education Program so we can continue to inspire young people to care about birds and learn how to protect it for the future.

Hello SBB'ers, Today, Linda Sullivan and I led a trip to Almaden Lake in San Jose joined by 11 enthusiastic birders who thoroughly enjoyed the show put on by the herons and egrets on the island, and great looks at a red-shouldered hawk harassing a red-tailed hawk, talons out!
We had a nice talk about heron breeding and nesting behavior and the importance of respecting nesting activity.
A few expected species were absent, but we saw all 4 herons and some were able to get looks at a Bald Eagle flyover and a fleeting look at a Hooded Oriole after listening to its 'wheet' call. Our total for the day was 38 species. https://ebird.org/checklist/S225318950

Hi all -
I led a store walk this morning at Shoreline Lake in Mountain View. We
parked on Terminal and walked along the south edge of the lake and then
looked over into the bay. I have to saw there was little action in the
songbird category. Other than a *NORTHERN MOCKINGBIRD* The *BROWN-HEADED
COWBIRDS* seemed to be the most vocal. Still a few *WHITE-CROWNED
SPARROWS* around and the only *GOLDEN-CROWNED SPARROW* we saw was still
going in breeding plumage.
The *AMERICAN SKIMMERS* were putting on a show as they flew around the
island several times. One pair were doing an impressive aerial maneuver
and were either courting or fighting. The *BLACK OYSTERCATCHER* was on
the island. Only one *AMERICAN AVOCET* was visible on the island, but
the *BLACK-NECKED STILTS* were found throughout our morning.
A pair of *SURF SCOTERS* were in the lake in addition to a few *COMMON
GOLDENEYES*.
When we turned to look out onto Pond A7 and Charleston Slough the most
numerous ducks were the *NORTHERN SHOVELS*. *RUDDY DUCKS* came in 2nd
with a few *CANVASBACK*, *CINNAMON TEAL*, and *BUFFLEHEAD DUCKS*. There
were loads of shorebirds out on the exposed mudflats but beyond where we
went today.
The *EARED GREBE* were in their beautiful breeding plumage. We also
observed both a *WHITE-TAIL KITE* and a female *NORTHERN HARRIER*.
The *BARN SWALLOWS* were the most numbers of our swallows.
Nothing terribly rare, but a great day to be on the bay. We ended with
52 species.

All.
For years Western Screech Owls were often heard, seldom seen, in our back yard. My wife and I then bought/built a nest box and mounted it in one of our Birch trees. We also bought a Trail Camera and a small solar panel to power it. Ultimately, we saw and photographed the Owls using the nest. The Owls then disappeared and we noted sticks protruding from the entrance to the nest box. Squirrels had packed the nest full of sticks and had damaged the entrance (a single Owl egg was found trapped inside). We eventually decided to remove the nest box as we could not stop the squirrels from damaging it and the old Birch trees were in bad shape (since removed). I then purchased a 12-and-a-half-foot pipe system designed to mount Purple Martin nest boxes and placed a new Western Screech Owl nest box on it. This is a squirrel proof system installed well away from trees and any property that might be damaged if it collapsed. Photo 3160 an adult at the entrance to the nest (about 7:30PM).The Owls have been using the nest box and as far as I know currently have young with multiple, nightly feeding trips to and from the nest. I have a recent photo with an adult feeding what appears to be a young Owl (with a light forehead and light throat, photo 5661).
It has been interesting to note that Owls, like many other birds, have multiple calls used at various times of the year (four to five that I have recorded) other than the Bouncing Ball call I am familiar with and that have not heard in the last few weeks. make sure the audioon the video is up high to hear it call as it flies away.

Canyon Wren is always great to find. That's been an occasional location in spring for decades, but most years they are not there. The rock is in fact "Alum Rock". The park was named based on the apparently-mistaken belief (according to wikipedia and others) that the rock contained alum.
