Visitors:
We had two visitors stop by the ridge including Linda from the Birds of
Prey Foundation.

Thank you to Clay Gibson, Mike Serruto, and Amy Walsh for your help looking
for migrants today!


Weather:
It was a sunny and warm morning with partial cloud cover that seemed to be
avoiding the ridge. Winds were out of the W across the metro area and the
state except for our little pocket of land that had E winds almost all day.
Heavier cloud cover came in the afternoon bringing cooler temperatures.
Wind speeds got up to a bft of 4.

Raptor Observations:
Migration was extremely stunted today with the W winds across the state and
S of us. The few migrants we had came along the ridge and W of us
relatively low. We got great looks at the American Kestrels that came by
late in the day.

Local Red-tailed Hawks seemed aggravated with everything today. Up to four
at a time could be seen mobbing Ravens, Golden Eagles, and each other. They
were mostly active in the morning and late afternoon.

Non-raptor Observations:
White-throated Swift 41, Broad-tailed Hummingbird 2, large gull sp. 1,
Double-crested Cormorant 1, American White Pelican 2, Say's Phoebe 1,
Black-billed Magpie 2, Common Raven 3, Black-capped Chickadee 1, American
Bushtit 3, House Finch 3, Pine Siskin 2, Spotted Towhee 1, Western
Meadowlark 1

Predictions:
We are hoping to get a push of migrants in the morning as rain is possible
in the afternoon. Bring a raincoat!

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.
