Visitors:
A pair of hikers came to the platform for the view and a photo. Several bikers and a few hikers and joggers were on the trail today.
Weather:
The day was chilly and completely overcast. Winds were predominately from the east at bft 3. The view was generally very good except for the 10-11:00am MST hour when visibility dropped for a while to about 5-6 km toward the south due to apparent snow showers; only very light snow fell at the HawkWatch platform. Temperatures rose from 1 C to 5 C.
Raptor Observations:
The travel paths of today's migrants were about evenly split between Dinosaur Ridge itself and the western ridges. The most notable pattern evident today was that the few migrants coming through were avoiding the snow showers along the foothills. No raptors migrated past the platform for about a two-hour window which included the period of time (10-11:00am MST) that snow fell to the south, west, and north. An early morning Osprey traveled the western ridges north. The American Kestrels and an adult Cooper's Hawk moved past close enough to the Ridge for good views. The last migrant counted was a nice Northern Harrier, with a lanky silhouette, gliding high, northward, directly over the Ridge. A local Golden Eagle was seen early in the morning, circling near the Lookout Mountain Towers. Local Red-tailed Hawks were observed hunting near Cabrini and in Rooney Valley, alternately coasting low or perch-hunting from trees or poles. A few local Turkey Vultures were also out and about.
Non-raptor Observations:
Very little Spotted Towhee singing was heard today, but those in the area did do a fair amount of whining, perhaps unhappy with the weather. A Broad-tailed Hummingbird, that had been heard ringing up and down the Ridge, was finally seen as he zipped across the platform near the end of the watch. A Rock Wren also made a few shy appearances. Also seen or heard were Common Raven, Audubon's Yellow-rumped Warbler, Black-billed Magpie, Woodhouse's Scrub-Jay, Mourning Dove, American Robin, and Western Meadowlark.

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 are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of the
Rockies 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 south
side of lot to 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.
