Weather:
Mostly clear early with clouds developing through the day to mostly cloudy with a sprinkle of rain by day's end. Light winds mostly around 2 Bft from shifting eastern directions. Temperatures in the 50's.
Raptor Observations:
Red-tails were active around mid-day. At one time five or six were sighted within the same binocular field south of the observation platform, though most were considered local. The several sets of good eyes were especially helpful in tracking local behavior vs. migrating flight. A few more migrating and local Red-tailed Hawks through the remainder of the day. There was no general flight path or height. A Peregrine moved from south to north over the ridge and was counted as migrating, but a short time later returned along a similar path from north to south and so was removed from the migration count. A local male Kestrel hovered just east of the ridge for several minutes.
Non-raptor Observations:
Also seen or heard: Black-billed Magpie, Townsend's Solitaire, Common Raven, Bushtit, Dark-eyed Junco, Black-capped Chickadee, Woodhouse's Scrub Jay, Rock Pidgeon. Two groups of American Crow numbering 7 and 9, four high spiraling Sandhill Cranes, and one Mountain Bluebird.
Predictions:
Hopefully the incoming front will offer more active migration.

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.
