Official Counter: Roger Rouch

Observers: Bill Wuerthele, Heidi Hayes, Jim Low

Visitors:
Dan and Purnee McCourt stopped by in the early morning for a pleasant
discussion about raptors, other birds, and geology.


Weather:
A pleasant day with temperatures from the low to upper 50's and light and
shifting winds generally from the east. Partly or mostly cloudy.

Raptor Observations:
Very generally, accipiters over the ridge in the morning with some quite
high and then Red-tailed over the west ridges in the afternoon. Some
western raptors were distant and beyond the west ridge line, and an
identification challenge. Local red-tails (probable) spiraled high over
the west ridge with no determined direction through much of the afternoon.
At a time seven raptors wandered north over or beyond the west ridge. Some
were local escorts and a few were migrating. Also, a few local Turkey
Vultures. The several pairs of good spotting eyes were a definite advantage
today.



Non-raptor Observations:
Seen or heard were Canyon Wren, Woodhouse's Scrub Jay, chickadee, Dark-eyed
Junco, Townsend's Solitaire, American Robin, Common Raven. Three elk on
the east flank of the ridge. A few White-throated Swifts buzzed by
overhead.


Predictions:
Could be a tough weather day or possible rain out?

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 are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies 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 south side of lot to 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.
