The predicted high winds held off until later afternoon making for pleasant
raptor watching. Temperatures in the 50's and 60's with light winds from
the E and SE in the AM and then from the NE and windy ending at about 5 bft
by days end. Partly and mostly cloudy with a light haze to the south and

Raptor Observations:
Highlights of the day were a group of ten Turkey Vultures that swirled
north up and over Mt. Morrison valley early and a higher flying
Broad-winged Hawk (spotted by Heidi) in the early afternoon over the Rooney
Valley. No real pattern to flight path other than an increase in elevation
later in the day, but few real eye strainers. Afternoon raptors seems to
tack effortlessly in the NE wind. Local TV's patrolled the ridge and
popped up and down from behind rocky ridge.

Non-raptor Observations:
Seen or heard were Bushtit, Dark-eyed Junco, American Robin. Common Raven,
Townsend's Solitaire, Spotted Towhee, Black-billed Magpie, Western

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
