Observation start time: 07:30:00
Observation end time: 10:30:00
Total observation time: 3 hours

Official Counter: Ajit Antony

Observers: Liza Antony

Weather:
Light winds from the West changing to ENE, temperature 27-34 degrees
Celsius, cloud cover 85-90%, which meant that had there been any migrants
we would have had an easier time finding them.


Raptor Observations:
Only one migrant, an adult CH at 8:35 AM MST which came directly from the
North.
Non migrant raptors: RT 2 adult, 3 immature over the watch, and distant RT
over the Western Ridge and Lookout Mountain; TV 6.
If any of you are wondering why we are counting so early by the end of
July when most hawk watches begin only by September 1, it is because Carol
had generously shared their observations from 2018-2020, and in 2018 as
early as August 5th they had had 4 Swainson's Hawk, 3 Ferruginous hawk and
2 AK, and I was wondering when the migration actually began here, hence our
presence.

Non-raptor Observations:
Rock Wren 3, Western Kingbird 2, Violet-green Swallow 2, Spotted Towhee 1,
Black-capped Chickadee 2.
Paragliders 4 to the NNW, starting at 11:00 AM MDT, and they soared quite
high indicating good lift.

Predictions:
The wind forecast on nullschool.net is from the NE which should give any
migrants a tailwind, so we will be at the watch for a few hours, at least,
starting with around 8:00 AM.

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)
