Visitors:
Today was Team Dino Hawk Count, a gathering of volunteers and other interested birders. Thank you all for your help. Visitors included David Gulbenkian, Janet Peters, Mark Chavez, David Starbuck, Steve Miller, Gary Rossmiller and Vonnie.

Weather:
We had nice weather and good cloud cover all day. Winds were primarily easterly.

Raptor Observations:
We counted several dark morph red-tailed hawks. Early the birds were close to the ridge. Mid day they moved out over the western ridge. Birds were moving high all day. We had several excellent looks at broad-winged hawks. There was a good push of American kestrels late in the count period. The first bird of the day was an osprey.

Non-raptor Observations:
The last bird of the day was a Flying V of 17 Sandhill cranes. We had two interesting groups of unknown gulls migrating, the largest more than 70 birds. They formed kettles and were taking advantage of thermals. We heard two broad-tailed hummingbirds, and saw several groups of white Pelicans.

Predictions:
Looks like it might be another 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 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.
