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

Official Counter: Santi Tabares

Observers: Doug Faulkner, Reed Gorner

Visitors:
Despite the nice weather less trail users, and only a handful briefly
stopped at the platform.


Weather:
Constantly shifting winds and cloud cover. Alternating between nearly
completely overcast to scattered clouds. Wind changing from completely calm
to strong northwestern gusts.

Raptor Observations:
Lots of movement early in the day, hawks moving along Green Mountain, Dino
Ridge, and over Mt. Morrison depending on weather at the moment. A lot more
migrants compared to previous few days, most of them in the early morning.

Non-raptor Observations:
Lots of Swifts flying by, with several swallows as well. Mountain and
Western Bluebirds made appearances throughout the day, and spotted some
deer at the bottom of the ridge and north of I-70.

Predictions:
More active migration.

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)
