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.

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.

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
