Observers: Laura Farnsworth

Visitors:
Thank you to Ajit and Liza Antony for bringing a DFO field trip up today to
the ridge. We had a busy morning full of visitors and the field trip, and
had a total of 9 visitors plus the 11 people in the field trip.

Thank you to everyone, including our volunteer Sara Painter, for their help
on the ridge today! It was a fun and busy day.


Weather:
Today was a beautiful day up on the ridge with cloud cover present most of
the day and temperatures around 22 C. Winds varied in direction throughout
the day, sometimes switching directions a few times within an hour.
Precipitation and heavy cloud cover was seen S and W of us in the late
afternoon. Some rain was present for about 10 minutes at the end of the
1500 hour, and nearby lightning cut the count 30 minutes short

Raptor Observations:
We had a slower day today than yesterday but got some great birds!
Migration in the morning was slow, but our visiting DFO group got to see a
late season Ferruginous Hawk migrate along the W ridge. We also had some
accipitrines move in the morning. A few more migrants came through in the
afternoon, mostly moving along the ridge and west of us. The highlight of
the day was a beautiful adult light-morph Swainson's Hawk that glided
directly overhead in the early afternoon. Birds were generally high today,
so getting a low SW was a treat!

Non-raptor Observations:
White-throated Swift 4, Broad-tailed Hummingbird 1, Feral Pigeon 1,
American White Pelican 15, Northern Flicker 1, Say's Phoebe 1, Blue Jay 1,
Black-billed Magpie 1, American Crow 2, Common Raven 2, Black-capped
Chickadee 1, Violet-green Swallow 1, swalow sp. 40, American Bushtit 2,
Rock Wren 1, American Robin 2, Pine Siskin 1, Spotted Towhee 1, Western
Meadowlark 1

Predictions:
Tomorrow will bring less cloud cover and winds from the W. Any day we will
begin to see Broad-winged Hawks!

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, and
American White Pelican. Birders of any skill level are always welcome. The
hawk watch at Dinosaur Ridge is staffed by Hawk Counter(s) and volunteers
from March through early May.

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)
