Visitors:
The muddy trail seemed to lower the number of hikers and bikers on the
trail today. A few came up but only for the view.


Weather:
The day was sunny with blue skies and zero cloud cover; by mid-afternoon, a
few tiny clouds formed then dissipated along the western ridges. A few
clouds finally rode the western horizon at the very end of the watch. The
patchy snow that covered Green Mountain, the western valley and the western
ridges thinned considerably as the day warmed during the watch from 10 C to
15 C. Mild winds (bft 1 and 2) were predominately from the east. Visibility
was good.

Raptor Observations:
Featureless blue skies made for a difficult watch. Luckily, the two morning
migrants (the Cooper's Hawk and the Osprey) were not "too high" to see
easily and came directly along the Ridge. A few hours passed before the
next migrant, a Red-tailed, was spotted with binoculars, far down the Ridge
and already very high. The last two migrants were caught in binocular scans
of the western ridges. The Swainson's Hawk's identity was confirmed as it
paused to circle up briefly near the Cabrini Shrine area and offered a view
of a lighter body with black-in-back flight feathers before it headed
north. In the morning, an apparently local Prairie Falcon, illuminated by
the sun bouncing off the snow, soared and circled very high over the
western valley but did not move north. Later, a local adult Cooper's Hawk
was spotted in the western valley as well, much lower in altitude. The
local Red-tailed Hawk pair sat together for a while on their favorite phone
pole in Rooney Valley in the morning. The local Turkey Vultures made
several rounds up and down the ridges and valleys.

Non-raptor Observations:
A Red-breasted Nuthatch announced its presence with its tinny voice, then
proceeded to inspect, carefully and quickly, a few trees near the platform.
Also seen or heard were Spotted Towhee, Black-billed Magpie, Western
Meadowlark, Black-capped Chickadee, White-throated Swift, Broad-tailed
Hummingbird, Western Bluebird, American Crow, Common Raven, Tree Swallow,
and Townsend's Solitaire.

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.
