Visitors:
9 visitors to the watch. Thanks to the help from Janet in the morning and Natalie in the afternoon and for each of their help this past month on Tuesdays during my counts.
Weather:
That day after a snowstorm, light winds from the ENE, high humidity with decreased visibility. There was a large area of fog far to the south which gradually made its way north partially covering Warren Peak. Dawson Butte could not be seen all day until the last one half hour. The lowest part of the trail to the watch was a sheet of clear ice from snow melting during the day and freezing at night. My crampons and Janet's YakTrax kept each of us stable and safe.
Raptor Observations:
Not much of a migration today, with no migrants in the morning and a smattering in the afternoon. Janet's observation was that at this watch, the day after a snowstorm has very few migrants, her hypothesis being that they are busy foraging for food which they could not find during the snowstorm, so tomorrow could be better for migrants. The best migrant of the day was a dark morph adult RT at 2:29 PM MST with a dark body and coverts and a light red tail, and just before that we had an adult male Northern Harrier â€" both of which were new for Natalie. That we could see 11 non-migrant RTs, and with favorable cloud cover, I'm guessing we weren't missing many migrants. An adult GE close enough to be naked eye to the north flew to the NW and dropped in front of the ridge, a non-migrant.
Non-raptor Observations:
Townsend's Solitaire 2, Woodhouse's Scrub-Jay 4, Spotted Towhee 1, American Robin 1, Common Raven 18, American Crow 5 , Northern Flicker 1, Bushtit 2, American Goldfinch 2.
Predictions:
The forecast is for mostly sunny skies with a high near 48°F, NW winds 6-10 mph with gusts to 16 mph.

Site Description
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Hawk watchers may
see 17 species of migrating raptors; and it is an excellent site to see rare
dark morph buteos including Broad-winged hawk, Swainson’s hawk, Ferruginous
hawk, Rough-legged hawk and Red-tailed Hawk. Other raptors we see include Golden
and Bald Eagles, Northern harrier, Osprey, Peregrine Falcons, Prairie Falcons,
Cooper's and Sharp-shinned Hawks, American Kestrels, Merlin, and Turkey
Vultures. American Goshawk is uncommon but also counted each season. Non-raptor
species include Rock Wren, Bushtit, Western Bluebird, Sandhill Crane,
White-throated Swift, American White Pelican, and Dusky Grouse. Birders of any
skill level are always welcome. The hawk watch at Dinosaur Ridge is staffed by a
Hawk Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs from the
southwest end of the parking lot to the hawk watch 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, and walk to
the flat area at the crest of the ridge. (Distance: 0.56 miles, Elevation gain:
259 feet)
