Erin Cockroft, a young photographer and bird entusiast, visited the site
(from Colorado Springs) for the first time and helped with spotting from
10-11 (MST). She found out about us searching the internet for places to
see hawks. Gave her our business card so she can check on our reports and
learn more. At the same time, a dozen middle-school aged mountain bikers
and adult leader took a lunch break on the platform (didn't ask any

Nice weather all count today. Slight breeze shifted from north to
southeast. A little hazy all day. (WU PWS Solterra)

Raptor Observations:
Migrating Raptors: A slow day. Busy early and late. Three species passed
close over the ridge at 8:00 MST (Coopers, Swainson's and TUVU). Then it
was mostly empty skies rest of the day. 

Non-Migrating Raptors: Several kettles of Turkey Vultures most of the
afternoon over the area from Flat Ridge to Mt Morrison, but I never saw a
single one go north from there beyond West Ridge. 

Non-raptor Observations:
Herd of 16 mule deer at base of bare slope. 

Non Raptors seen or heard: White-throated Swift (n=16), Woodhouse's
Scrub-Jay (3), Black-billed Magpie (2), American Crow (2), Mountain
Chickadee (15), Brown Creeper (2), Mountain Bluebird (1), Townsend's
Solitaire (2), Dark-eyed Junco (Slate-colored) (2), Spotted Towhee (1),
Western Meadowlark (1), House Finch (1).  

Mountain Chickadees: A series of pairs moved quickly north on the ridge,
pausing in the junipers, then continuing, in a group of about 12. 

Swifts: Flew over in small groups all day, close to the ridge. 

Reported on eBird. 

Like Mitchell suggested, no point in predictions. Today seemed like ideal
conditions, from a personal and land-based species perspective.

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
