Observation start time: 09:00:00
Observation end time: 16:00:00
Total observation time: 7 hours

Official Counter: Debbie James

Observers: Carol Cwiklinski, Robert Klipp, Steve Small, Susan Blansett

Visitors:
We set up north of the station, and so only had a couple of people stop to
talk.


Weather:
Windy day. Once the temperature came up it made being on the Ridge a
little more comfortable. High-ish humidity up to 40%.

Raptor Observations:
Bonanza day for Red Tail migrators. Also wonderful seeing the peregrines,
Golden and Bald Eagles, and Merlins. Locals observed: at least 3 Red
Tailed Hawks; one Golden Eagle; and a pair of American Kestrels. Most
migrators were above the Ridge or close to it, and also very high, catching
thermals that zoomed them north FAST. No flapping with those hawks.
Sharpies were low and easy to see, as well as the Bald Eagle, who was very
spectacular.

Non-raptor Observations:
Other species heard or seen: 1 Woodhouse's Scrub Jay; 13 Common Ravens
including a couple flying an elaborate courting display; 13 American Crows;
2 Townsend's Solitaire; 9 American Robin; 1 Mountain Bluebird; and
Hooray--our first White Throated Swift for the season.

Predictions:
Hopefully another heavy day for migrating raptors.

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)
