Official Counter: Emma Riley
Observers: Dave Erickson, Edie Israel, Janet Peters, Mariane Erickson
Visitors:
Janet Peters, Edie Israel, Mariane Erickson, and Dave Erickson helped
observe today. We had a total of 23 visitors at the Hawk Watch today stop
by or ask questions.
Weather:
Clear skies all day with a haze that settled in towards the end of the day
reducing visibility just a bit. Winds were moderate from the NE today and
could be felt on the east side of the platform all day but not the west
side, providing some relief.
Raptor Observations:
The morning started off right away with a handful of accipiters. High
numbers of AK seen early in the day, leading into decent TV movement in the
afternoon. One kettle of 10 TV was seen at two different spots on the
ridge, followed by a few very close TV overhead. Local RT and TV activity
was high today.
Non-raptor Observations:
A large group of Cedar Waxwings was seen moving before the count started.
Corvid activity was moderate all day, with some Common Ravens seen
harassing migrant raptors. Another Western Meadowlark was heard in the east
valley. Overall passerine activity was low today.
Predictions:
North winds that are lighter than the last three days. Strong sun and low
cloud cover expected.

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)
