Visitors:
Ajit and Liza Antony observed from 0900-1200 MST. They are very skilled hawk watchers visiting from Mount Peter Hawk Watch in New York. Ajit's scope was very helpful with far birds, and both were excellent observers.
Weather:
Winds were Northeast around 5 for the first hour of the day. From 1000-1430 MST winds had an easterly component East/Southeast and generally light 0-5 mph.
Raptor Observations:
The first raptor of the day was at 0850 close to Dino Ridge on the east side. From 0930-1150 raptors generally flew along the ridge west of Dino, often gaining height on the slopes of Mount Morrison. At 0955 we had an unusual sighting of three osprey in a kettle at the south end of Dino Ridge,they gained height and flew North together high (2) and just west of Dino. Beginning around 1200 and continuing until 1330 raptors moved close to observation. They began forming kettles at the south end of Dino Ridge often in groups of five or more. A couple notable examples include; at 1308 ten red tailed hawks and one sharp shinned hawk formed a kettle, at 1315 11 red tailed hawks and one ferruginous hawk formed a kettle, at 1325 two northern harrier and two American kestrels formed a kettle. The kettles generally gained height south of observation and continued north high (1-2) along Dino Ridge. Raptors moved away from Dino around 1400 hours and continued migrating along the western ridgeline until the end of day. Birds were still moving along that ridge line as I was closing for the day, but I was unable to continue counting. My last bird at 1417 was an immature Swainson's hawk.
Non-raptor Observations:
White-throated swifts

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.
