Observers: Claude Vallieres, Mike Ramee



Visitors:
We were helped by 4 skilled visitors: Volunteer Jefferson Open Space Ranger Rob Reilly, John Dwyer and two persons who had participated in Hawkwatch in the early days of sponsorship by Denver Museum of Natural History. They were Kathryn Dins and Mike Ramee. Mike Ramee had helped construct the viewing area, positioning stones and gravel. It was very helpful to have experienced eyes finding and identifying the birds.

Weather:
A very fine day with unlimited visibility and wind from 4 to 8 mph, few clouds and temperatures ranging 34 to 50 degrees Fahrenheit.

Raptor Observations:
The exciting observations were between 11:00 and 12:00 MST. Two adult Bald Eagles, a Golden Eagle adult and an adult Harlan's Red-tailed Hawk migrated by, all within about 10 minutes.

Non-raptor Observations:
American Robins 6, Townsend's Solitaire 3, Black -billed Magpie 5, Eurasian Collared-Dove 1, Western Meadowlark 2, Scrub Jay 1, American Crow 10, Mountain Chickadee 2, Common Raven 6, Dark-eyed Junco 20.

Predictions:
More sun.

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.
