Observation start time: 09:00:00
Observation end time: 15:00:00
Total observation time: 6 hours

Official Counter: Pam Batton

Observers: Kathy Holland

Visitors:
3 birders joined us for most of the am. Around noon 2 birders joined us for
about an hour. A couple of the visitors from DFO. Thanks for the extra
eyes!


Weather:
The evening before had a storm of mixed rain and snow. Snow did not stick
on the ridge, but the temperatures were cool and the site shrouded in low
clouds for the first hour. Took most of the day for the haze to burn off
the horizon. Green Mountain difficult to see till almost noon. Last hour
had wind gusts.

Raptor Observations:
Most observations to the west of site, due to wind direction and heavy haze
to east.

An immature red-tailed hawk gave us a grand view as it perched on a snag
next to the site. It seemed unconcerned about us and stayed for over 15
minutes. Never did go further north.

Non-raptor Observations:
Magpies very active along the ridge. Ravens very active all around us.
Black-capped Chickadee, Solitaire, Scrub Jay

Best siting was 4 White-throated Swifts migrating through

Predictions:
The variety of species is increasing. The day should be good with the storm
having blown out by today.

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)
