Visitors:
There were very few people on the Ridge today, and no one stopped by the observation site.
Weather:
The day was partly cloudy, with cloud cover ranging from 20% to 70%. Wind out of the southeast in the morning shifted to the east about midmorning and continued as a constant easterly breeze for the remainder of the observation period (2 - 4 bft.). Temperatures: low of 39 and a high of 45 F.
Raptor Observations:
Migrating Raptors: There were eight migrating raptors, seven Red-tailed Hawks and one unidentified falcon - at the limit of 8x binoculars. Two groups of migrants, three of the Red-tailed Hawks observed in the morning and two of the afternoon Red-tailed Hawks, appeared to be moving together, as they passed the site in quick succession. All of the migrants were on a similar path - moving above the valley to the east of the West Ridge. Non-Migrating Raptors: Local Red-tailed Hawks were active through much of the day. A local Cooper's Hawk and a local male American Kestrel made brief appearances.
Non-raptor Observations:
Non-Raptor Observations: The following species were seen or heard: Bushtit, Townsend's Solitaire, Mountain Chickadee, American Robin, American Crow, Common Raven, and Black-billed Magpie.

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 the Rocky Mountain Bird
Observatory from about 9 AM to around 4 PM from the first week of March to the
first week of 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 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.
