Visitors:
Only one visitor to the platform today, and he did ask about our findings.
He was the only one even on the trail up the ridge.
Weather:
xVery bright morning, mostly clear skies. Heavy clouds gradually increased
above the western horizon. Snow and very low visibility moved in at 15:00
and we ended the watch at 15:30 MST.
Raptor Observations:
First migrating raptor was at 12:30 (three hours into the watch), an adult
Bald circling very high up and then disappearing into the clouds to the NW.
Another adult and then a subadult (2nd-3rd yr) followed the same flight
pattern within 20 min. Fourth Bald was adult and flapping constantly rather
than up a column. Fifth Bald was a subadult and moved directly overhead.
Local immature Golden flew right at us to the point we almost ran for
cover.
Ben is an experienced birder and an environmental educator. He jumped right
up to speed. Looking forward to continuing to work with him this season.
Non-raptor Observations:
Observed: Canada Goose flyover (3), Woodhouse’s Scrub-Jay (2),
Black-billed Magpie (4), Common Raven (9), Mountain Chickadee (2), Bushtit
(37) and Townsend’s Solitaire (2).
Predictions:
Trail Conditions: Powder on the way up, mud & snow on the way down. Expect
muddy trail conditions on Tuesday.

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)
