We had many visitors to the platform today and this time most were curious
about our project. Handed out one info card to a family with a daughter who
asked us several questions.

Good weather today for people and birds. Wind and clouds arrived late in
the watch.

Second location: 50 meters down southeast side of Two Pines.

Cooper's Hawk 4, Northern Goshawk 1 adult, Red tailed Hawk 30 (3 dark

compares with 31 total migrating birds seen from the platform.)

Migrating Raptors: Migrators were all over the place today. Some east, some
directly overhead, and some west; some beyond naked eye, and some just
above us over the ridge. Good thing there were three of us most 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 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
