Dinosaur Ridge - Denver Field Ornithologists
Colorado, USA
Visitors:
Despite the nice weather less trail users, and only a handful briefly stopped at the platform.
Weather:
Constantly shifting winds and cloud cover. Alternating between nearly completely overcast to scattered clouds. Wind changing from completely calm to strong northwestern gusts.
Raptor Observations:
Lots of movement early in the day, hawks moving along Green Mountain, Dino Ridge, and over Mt. Morrison depending on weather at the moment. A lot more migrants compared to previous few days, most of them in the early morning.
Non-raptor Observations:
Lots of Swifts flying by, with several swallows as well. Mountain and Western Bluebirds made appearances throughout the day, and spotted some deer at the bottom of the ridge and north of I-70.
Predictions:
More active migration.

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.
