Visitors:
A serious younger birder stopped by to check on the daily count. Plus several of the usual fair weather weekend hiker's checking out the view.
Weather:
A mild day with temps rising from the mid-forties to the low 60's F and a breeze from the SE around 1 or 2 Bft. Clear skies to start the day, but by mid-day it was mostly overcast with thin clouds and a light atmospheric haze overhead.
Raptor Observations:
One or two naked eye birds with the remainder being binocular spots both overhead and along the western ridges. A few more accipiters than previous days and migration seemed a little later in the day. The overhead haze limited visibility for high fliers. There was some local Red-tailed activity in virtually all directions, but especially around Cabrini.
Non-raptor Observations:
A Canyon Wren was heard singing in the early morning and then in the afternoon. About 15 or 20 White-throated Swift buzzed around Mt. Morrison and twelve mule deer roamed the slopes around Cabrini. Black-billed Magpie, Western Meadowlark, Common Raven, Woodhouse's Scrub-jay, Northern Flicker, Spotted Towhee, Townsend's Solitaire, American Robin. And...a vintage P-51 Mustang.
Predictions:
My predictions have not be very accurate this season, but it is probably coming up on peak migration and it should be a good day.

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.
