Official Counter: Bill Wuerthele

Observers:

Visitors:
There were just a few intrepid hikers and trail runners willing to brave
the snowy and muddy trail today. On couple stopped by to ask about the
HawkWatch Program and hawk migration in general.


Weather:
Last night's storm dropped about 2 inches of snow on the ridge, and
lingering heavy, low clouds limited visibility to about 2 kilometers
throughout the watch period - Mt. Morrison and the West Ridge were hidden
by clouds. The morning was calm, with a slight breeze (2 bft) from the
east in the afternoon. Temperatures ranged from 34 - 40F.

Raptor Observations:
Migrating raptors: There were nine migrating raptors - four American
Kestrels, two Cooper's Hawks, two Red-tailed Hawks, and one Osprey. The
Kestrels came directly up the ridge and passed over the observation point
just above the tree tops. The other migrants, except for an adult
Red-tailed Hawk, passed by the east side of the ridge at or below eye
level. The highlight of the day was a close-in look at the Osprey at eye
level.

Non-migrating raptors: There was very little local raptor activity, with
just brief appearances by two Red-tailed Hawks on the east side of the
ridge.

Non-raptor Observations:
Non-raptor observations: The following species were seen or heard - Western
Meadowlark, Black-billed Magpie, American Robin, Dark-eyed Junco
(Gray-Headed), Townsend's Solitaire, Northern Flicker, and Bushtit.

Predictions:
Tomorrow' predicted warmer, clearer weather might bring storm-delayed
migrants - could be a good day. Be prepared, the trail is quite muddy.

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.
