Visitors:
Today was our Rapthorton! We owe a huge thanks to everyone who came out for
both the raptorthon and for the normal count today- Carol Cwiklinski, Steve
Small, Janet Peters, Natalie Vande Vuss, Joey Kellner, Robin Sher, Seth
Cutright, Julia Guian, and others. Total visitor count was up to 68 people
at the Hawk Watch today.
Weather:
Clouds were present all throughout the day to varying degrees. Winds stayed
calm for most of the day coming from the NE. The sun was out every once in
a while, warming the ridge up. A thick haze settled into the distance early
in the day, decreasing visibility.
Raptor Observations:
Our best day yet this season happened to fall on our Raptorthon, how great!
254 migrants, FOY SW and BW were seen today. We got great looks at both
species, as well as OS, CH, AK, GE, RT, TV, PG, and BE. Overall, an
incredible day for migration and for those of us who got to witness.
Non-raptor Observations:
Predictions:
Winds predicted from the W reaching speeds of 40 mph. Some cloud cover.

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)
