Visitors:
A dozen or so on the trails. Half that visited the platform. One was interested in what we were doing.
Weather:
As last nights storm exited it left the morning with cold temps 1 C and haze on the horizons. Finally reached 8 C around 2 pm.
Raptor Observations:
Red-tails continue courtship displays although less dramatic than past weeks. Few flew directly over the ridge today. The traffic was heavy in the am on the Green Mountain side. Winds shifted for the afternoon and took most of the raptors across the west ridge and Cabrini. Birds increased between noon and 2pm.
Non-raptor Observations:
Solitaires actively singing. Many magpies. Many ravens enjoying a good soar.
Predictions:
Looks to be an active day. Might be high with increased thermal activity and rising air temps.

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 of any skill level are always welcome.
HawkWatch at Dinosaur Ridge is generally staffed by volunteers 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
southwest end of lot to the 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.
