Dinosaur Ridge - Denver Field Ornithologists
Colorado, USA
Visitors:
3 birders joined us for most of the am. Around noon 2 birders joined us for about an hour. A couple of the visitors from DFO. Thanks for the extra eyes!
Weather:
The evening before had a storm of mixed rain and snow. Snow did not stick on the ridge, but the temperatures were cool and the site shrouded in low clouds for the first hour. Took most of the day for the haze to burn off the horizon. Green Mountain difficult to see till almost noon. Last hour had wind gusts.
Raptor Observations:
Most observations to the west of site, due to wind direction and heavy haze to east. An immature red-tailed hawk gave us a grand view as it perched on a snag next to the site. It seemed unconcerned about us and stayed for over 15 minutes. Never did go further north.
Non-raptor Observations:
Magpies very active along the ridge. Ravens very active all around us. Black-capped Chickadee, Solitaire, Scrub Jay Best siting was 4 White-throated Swifts migrating through
Predictions:
The variety of species is increasing. The day should be good with the storm having blown out by today.

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.
