Visitors:Only 3 visitors who were interested to know what we were doing.
Weather:Warm, 68 deg F to 79 deg. F, with high, thin clouds until 15:00 MST when
the sky became dark. Wind was calm from ESE, changing to SW at 12:00 with
a few gusts but still very calm. Visibility unlimited, no precipitation.
Raptor Observations:A local immature Red-tailed Hawk with one missing left primary,a missing
tail feather and some secondaries of different length is recognizable from
other days. A local adult Sharp-shinned Hawk was seen twice. A local
Golden Eagle passed, also with primary molt visible. It was judged to be
local because of the late date.
Non-raptor Observations:
A pair of Spotted Towhees were seen with nest material and much excited
behavior under the juniper that is next to the large fence post just a few
feet SW of the hawkwatch platform. Will they stay?
Ten Chipping Sparrows and one male Broad-tailed Hummingbird were added to
the usual local birds today.

Dinosaur Ridge information may be found at:
http://www.rmbo.org/Site DescriptionDinosaur 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.
