Visitors:
Two hikers stopped for a brief talk.
Weather:
Warm with temperatures topping in the mid-seventies. Partly cloudy early, clearing during the day with a dusty haze over the eastern plains in the afternoon. Calm early in the day with increasing winds generally from the southwest. Very windy in the afternoon with gusts greater than 30 mph.
Raptor Observations:
Migrating raptors were seen both over the west and Green Mountain ridges, generally at long distances. Local red-tails observed over Green Mountain and Cabrini in the morning. Two quick looks at local unidentified falcons. Raptor sightings decreased significantly in the afternoon, possibly due to the high winds.
Non-raptor Observations:
Single or few numbers of birds that were heard or observed in the morning included black-billed magpie, chickadee, solitaire, western meadow lark, spotted towhee, and robin. A group of 6 crows. A few raven braved the afternoon winds. About ten elk grazed on a ridge near Cabrini.
Predictions:
Possibly a return to the higher counts of the past few days with more normal wind speeds?

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.
