Visitors:
Two pairs of hikers stopped for a brief explanation of our activities.
Weather:
A mild day all around with mostly sunny skies in the morning becoming mostly cloudy with a light atmospheric haze. Temperatures from the upper 40's to the mid-60's. A light breeze around 1 Bft. from the SE in the morning shifting to a light northerly wind around 2 Bft.
Raptor Observations:
Roughly half or more of the migrating raptors were over the west ridge and required binoculars to spot and often the aid a scope in identification. The remainder were pretty much a mixed bag in location and height flight. The early part of the day was slow but the 10:00 to 11:00 hour (MST) had 31 migrating raptors that included a kettle of 18 Turkey Vultures and a smaller loose kettle with 3 Red-tailed Hawks, 3 Turkey Vultures and an accipiter. The afternoon had close views of a Peregrine Falcon, Prairie Falcon, and a dark Red-tailed. The local Red-tails and Turkey Vultures were enjoying the good thermals.
Non-raptor Observations:
Seen or heard were Spotted Towhee, Common Raven, chickadee, Townsend's Solitaire, 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 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.
