A gentleman visiting from Austin had seen the Hawkwatch reports and came up
for about an hour mid-morning to do bird photography. Unfortunately the
raptors and other birds were all pretty far away.

A warm but windy day with temperatures in the 60's and wind shifting from
the west and north at around 3 or 4 Bft. in the morning, then 5 or 6 Bft.
in the afternoon. Mostly clear in the morning and then partly cloudy. A
few raindrops in the afternoon.

Raptor Observations:
Only a few migrating raptors all in the morning hours, but some good
entertainment from local raptors. A male and female Kestrel became very
intimate on one of the power poles just to the east and later chased a
Cooper's Hawk moving north to do an about face and fly south. A group of
three to five Turkey Vultures roamed above the ridges through the day. A
local Golden Eagle and Red-tailed Hawk performed some aggressive acrobatics
together over the eastern ridge. And of course the occasional local

Non-raptor Observations:
Seen or heard included Woodhouse's Scrub-jay, Canyon Wren, Western
Meadowlark, American Robin, Spotted Towhee, Blue Jay, Townsend's Solitaire,
Common Raven, Violet-green Swallow. White-throated Swifts were common from
mid-morning forward.

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
