Observation start time: 10:00:00
Observation end time: 16:00:00
Total observation time: 6 hours

Official Counter: Debbie James

Observers: Jim Esten, Susan Blansett

Visitors:
We set up north of the platform, and so had very few visitors.


Weather:
Blasting HOT!! It was 76 degrees F when we left the Ridge. Very low
humidity, and the entire Denver basin was enveloped in a yellow haze
(pollution?), until mid afternoon.

Raptor Observations:
Two local Red Tail Hawks seen courting the first hour. Pitiful number of
migrants, especially for April. All traveled directly over the Ridge.

Non-raptor Observations:
Seen or heard: Flicker 1; Crow 2; Raven 1; Robin 1; Big kettle of something
the size of crows over the West Ridge; Woodhouse's Scrub Jay 3;
Black-capped Chickadee 3; White-breasted Nuthatch 1; 6 Canada Geese flying
in tandem north; House Finch 6; Solitaire 3; Western Bluebird 1; Magpie 1.

Predictions:
Hopefully better than today as far as migrating Raptors are concerned.

Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders of any skill level are always welcome. HawkWatch at
Dinosaur Ridge is generally staffed by volunteers from about 9 AM to around
3 PM from March 1st to May 7th.

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 small signs from
the southwest end of lot to the hawkwatch 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,
head through the gate, and walk to the clearly-visible, flat area at the
crest of the ridge. (Distance: 0.56 miles, Elevation gain: 259 feet)
