Two separate fellows who had observed during the museum days stopped by for
a short talk.

A brisk wind of 3 or 4 Bft from the NW ushered in the first day of the 2017
season. A virtually cloudless day with winds continuing all morning and a
relatively calm afternoon. Temperatures rose from the upper 20's to the
low 40's F. There was a dusting of snow on the ground to the west and bare
ground to the east.

Raptor Observations:
Two migrating Red-Tailed Hawks were recorded. Possibly a typical slow
early season day or unfavorable winds? A few sightings of adult local
Red-tailed Hawk(s) over Matthews-Winters.

Non-raptor Observations:
Non-raptors birds were few and included Common Raven (several), American
Robin, Black-billed Magpie, and Townsend's Solitaire.

Hard to say? Maybe a better wind direction or better thermals will give
better numbers, but it's early yet.

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
