Visitors:
None.
Weather:
Pleasantly cool with temps in the upper 20's and low 30's with a light breeze generally from the SE. Mostly cloudy with a late break in the clouds and sun at day's end.
Raptor Observations:
Two Golden Eagle were first observed flying tandem over two humps and proceeded to spiral over the southern end of the ridge then over the observation site and north out of sight. A brief talon grapple was suspiciously like local behavior, but both were counted as migrating. Also, to acknowledge the common sighting of local Prairie Falcon, but the one counted as migrating was on a direct flight north out of line of sight. About ten local Red-tailed Hawks were sighted or re-sighted. Also, a local Kestrel.
Non-raptor Observations:
Few non-raptors with a couple of marauding Black-Billed Magpie, a Scrub Jay, and a chickadee.
Predictions:
The next couple of days should be the first days of warm sun for sometime, which may bode well for more activity. Note that the trail is packed snow, but will be icy or sloppy for a while. The observation site has small areas of bare ground starting to show.

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 the Rocky Mountain Bird
Observatory from about 9 AM to around 4 PM from the first week of March to the
first week of May.
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 ridge.
