Visitors:
None.

Weather:
Initially decent visibility quickly diminished as a storm moved in from the east and north. Near freezing temperatures and a few inches of new snow from the previous night. The watch was ended early due to poor visibility, moderate snowfall, and a forecast for the same, although I had second thoughts when getting back to town and better weather.

Raptor Observations:
One migrating Cooper's and a local Prairie falcon.

Non-raptor Observations:
Also seen or heard were Western Meadowlark, Common Raven, Black-billed Magpie, and American Robin.

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.
