Visitors:
Today was Team Dino Hawk Count, a gathering of volunteers and other
interested birders. Thank you all for your help. Visitors included David
Gulbenkian, Janet Peters, Mark Chavez, David Starbuck, Steve Miller, Gary
Rossmiller and Vonnie.
Weather:
We had nice weather and good cloud cover all day. Winds were primarily
easterly.
Raptor Observations:
We counted several dark morph red-tailed hawks. Early the birds were close
to the ridge. Mid day they moved out over the western ridge. Birds were
moving high all day. We had several excellent looks at broad-winged hawks.
There was a good push of American kestrels late in the count period. The
first bird of the day was an osprey.
Non-raptor Observations:
The last bird of the day was a Flying V of 17 Sandhill cranes. We had two
interesting groups of unknown gulls migrating, the largest more than 70
birds. They formed kettles and were taking advantage of thermals. We heard
two broad-tailed hummingbirds, and saw several groups of white Pelicans.
Predictions:
Looks like it might be another good day!

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)
