Partly cloudy, calm and seasonably warm, if not hot. A breeze from the NE
around 0-1 Bft. early then from the NW around 1-2 Bft. Temps rose from the
lower 50's to lower 70's.

Raptor Observations:
Raptors appeared to enjoy the good thermals of a warm calm day. Of five
migrating, four were "at the limit of 10X binoculars". Local raptor
activity was relatively light. Three or four probably local high spiraling
Red-Tailed were lost in the blue or clouds before any sense of flight
direction could be determined.

Non-raptor Observations:
Also seen were Black-billed Magpie, Common Raven, American Robin,
Townsend's Solitaire, Western Scrub-Jay, Mountain Chickadee. A band of
eight or ten Bushtit twittered through the brush in the afternoon.

The schedule doesn't show a counter for tomorrow, Thursday. If the calm
and warm weather persists, a guess would be for high fliers as thermals

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
