Dinosaur Ridge - Denver Field Ornithologists
Colorado, USA
Visitors:
19 visitors came to the platform. Jeff Birek, former director of Hawkwatch for the Bird Conservancy of the Rockies, shared his expertise for most of the day. New volunteer Vicky Hamilton was very helpful with spotting.
Weather:
Warm and windy until about 2:00, when the wind died and bit of sun shone through the cloud cover.
Raptor Observations:
The Turkey Vultures were seen from considerable distance, while the accipiters were low and close to the ridge. Resident Red Tailed Hawks were observed throughout the day both east and west of the ridge. A resident juvenile Golden Eagle was seen out over the Chatfield area. A probable Northern Goshawk flew south from the ridge. Also seen was a Prairie Falcon.
Non-raptor Observations:
Also observed were Black Billed Magpie, Black Capped Chickadee, Common Raven, Rock Pigeon, Woodhouse Scrub Jay, Townsends Solitaire, Violet-Green Swallow, Bushtit, Mountain Chickadee, White-Throated Swift, Spotted Towhee, Dark-Eyed Junco, and Northern Flicker
Predictions:
Could be a good day early, before the rain.

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 of any skill level are always welcome.
HawkWatch at Dinosaur Ridge is generally staffed by volunteers 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
southwest end of lot to the 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.
