Visitors:
A visitor reported a rattle snake on the trail and that a dog had been bitten.

Weather:
Warm, 17 to 24 deg C with a thin high altitude haze in the morning which became full cover with mid altitude cumulus by noon. A pleasant breeze from the east changing to west after noon. Visibility unlimited.

Raptor Observations:
Nearly all raptors seen were very high, directly over Dinosaur Ridge. The exception was the local Cooper's Hawk which appeared at various levels from bottom of the ridge to the top.

Non-raptor Observations:
Birds were quiet. The Rock Wrens seem to be nesting nearby. The Western Scrub-Jay pair is around but may be nesting not so near. Swallows were very numerous but seen only in silhouette with binoculars. There's a tan lizard, fat and 6 inches in all and with a pinkish tail.

Predictions:
May luck bring more hawks.

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 the Rocky Mountain Bird
Observatory from about 9 AM to around 4 PM from the first week of March to the
first week of May.

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.
