Visitors:
A few curious hikers.
Weather:
In spite of moderate temperatures in the mid 30's and 40's, a brisk northeastern wind around 3 Bft, a mostly cloudy day, and higher humidity gave a chill to the air. Moderate atmospheric haze.
Raptor Observations:
The flight pattern today included many raptors close to the ridge above and below eye level, apparently using ridge lift and wind rather than thermals. Some made northern flight seem effortless against a northern wind. Flat light and some haze lead to many identifications by silhouette and flight characteristics. Local falcons were sighted more than once and a Peregrine and Prairie Falcon gave every indication of migrating and were added to the tally. Local Red-tailed were active often below eye level. Also a local Cooper's and a few local Turkey Vultures.
Non-raptor Observations:
Songbirds travelling in small groups of 2s,3s or more were common especially in the early hours. Some were speculated as Yellow-rumped Warblers and two Yellow-rumped landed in the dead pine near the platform. Some unk. swallows and others not identified. Also seen or heard were Broad-tailed Hummingbird, Western Meadow Lark, American Robin, Common Raven, Woodhouse's Scrubjay, White-throated Swift,Black-Billed Magpie, Rock Pigeon, Morning Dove, chickadee, and Dark-eyed Junco.

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.
