Lots of cyclers and hikers today on the Ridge. One group spent some time
at the station, they were on a leadership training for their activist
group--and got to see a migrating Redtail--along with a local, which
interested them.

Hot, bone dry day up on the Ridge, which is under fire ban. Some haze to
the west early on, then that haze blew away, leaving haze to the south.

Raptor Observations:
What a day! 7 local Redtail hawks were spotted, two appeared to be mating
in the first hour. 2 local Kestrels. Had at least one migrating hawk
every hour, with the 1000-1100 hour having 12! It was nice seeing Coopers
and Sharp-shinned today. Some of the raptors were flying so high and far
over West Ridge, that without a scope, we weren't able to identify the

Non-raptor Observations:
No mammals spotted today, but bird-wise there were 6 Black-billed Magpie;
44 American Crows; 3 American Robins; 2 Townsend's Solitaire; 2 Western
Meadowlark; 3 Western Scrub Jay; 2 Chickadee (species) heard; 1 Flicker; 25
Bushtits; 1 Housefinch; 25 Rock Pidgeons; 1 Common Raven

Going to be a HOT one tomorrow. Hopefully hawks will find it as amenable
to migrating as they did today.

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
