Visitors:
There were only a few people on the trails and no visitors to the platform. Camille Schiraldi, new to HawkWatch but not new to Raptor Monitoring, helped count our first migrant of the season—another set of sharp eyes made it much easier to watch that the northward-heading Red-tailed Hawk did not return south (like a local Red-tailed might…)
Weather:
The partly-sunny day with 70-percent cloud-cover (mostly thin and translucent) shifted quickly to a grayer, overcast day with 90-plus-percent, thicker cloud-cover. Thinning snow still covered most of the valleys and ridges. The winds, predominately from the north and northeast, were initially calm but picked up as the afternoon progressed to bft 2-3. The temperature on the platform held at 7 C for most of the time but dipped a degree or two toward the end of the watch. Visibility along the upper ridges was acceptable (at least 10 km), but a dirty white haze in the valleys to the south reduced visibility to maybe half that.
Raptor Observations:
All today's migrants used powered flight as they passed low and to the east of Dinosaur Ridge. Two of the Red-tailed migrants did attempt to circle up a bit over I-70 before continuing north. The highlight of the day was the adult Bald Eagle that wasted no time powering past; the tip of its otherwise very white tail showed faint red-brown muddy smudging. A couple of local Red-tailed Hawks were seen at the end of the watch: one flew north close to the platform but quickly returned south, while the other crossed Rooney Valley to drop down near the road on Green Mountain before it too returned southwest toward the Ridge.
Non-raptor Observations:
Also seen or heard today were Townsend's Solitaire, Rock Pigeon, Woodhouse's Scrub-Jay, American Crow, American Robin, Common Raven and Black-billed Magpie.
Predictions:
The trails and the HawkWatch platform will likely be icy in the morning.

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 ridge.
