Total observation time: 2.5 hours

Official Counter: Ajit Antony

Observers: Liza Antony

Weather:
Light winds from the east, temperature 23-24 degrees Celsius, steady
barometer, clear visibility to 24 km. by 8:30 AM MST small puffy thermals
were developing at different areas between North and SW, and by the time I
left they were a broken chain of cloud low over the western ridge, but with
no raptors within it or above it.

Raptor Observations:
The first raptor seen was a non-migrant TV at 7:32 AM MST. The first
migrant was an SW at 8:45 AM, and the only other migrant was an immature RT
6 minutes later.
Non-migrant Raptors RT 2, TV 3

Non-raptor Observations:
Bushtit 3, Broad-tailed Hummingbird 1 male, Black-chinned Hummingbird
female 1, Lesser Goldfinch 4, Woodhouse's Scrub-Jay 1, House Finch 2.

Predictions:
Like today but with the winds coming from the NE, could be favorable.

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 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)
