Visitors:
Deb Bogar, Gary Rossmiller, Barbara Bank, Debbie James, and Ed Imatani
observed today. Gary and I usually count on different days so it was great
to meet him and bird with him today.
Weather:
Heavy fog for the first few hours of the morning, lifting in the early
afternoon to reveal scatted rainstorms around us. Winds were light until
early afternoon, shifting from E to N throughout the day. Wind picked up to
about 27 km/h at points in the late afternoon. Storm clouds moved into our
area at 1430, ending the count early.
Raptor Observations:
Migration was slow today but local raptor activity was high and exciting.
One local PEFA was seen, as well as one TUVU, three GOEA, and one COHA. One
migrating juvenile RTHA gave us great looks early in the day.
Non-raptor Observations:
Passerine activity was low today. Corvid activity was also slightly lower
than normal today, with only 6 American Crows and 3 Common Ravens seen all
day.
Predictions:
Tomorrow should be a relatively good day. SW/SE winds predicted with some
cloud cover and warmer temperatures than today. The trail may be muddy in
the morning, but it should hopefully be dry by the end of the day.

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. (Distance: 0.56 miles, Elevation gain: 259 feet)
