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

Weather:
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.

Predictions:
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 ridge.
