No visitors. Very few hikers and no bikers were seen on the slushy, muddy
trail today.

The mild, sunny day was brightened even more by the snow cover on the
ridges and in the valleys. Cloud-cover consisted of extremely thin,
translucent cloud-veils and dissipating contrails; it never topped 50
percent. The winds were calm (bft 1-2). Temperatures rose from about 7 C to
12 C. Visibility was generally good, but an orange-brown pall hung in the
Denver Basin in the morning.

Raptor Observations:
Snow cover along the ridges and valleys made it easy to follow low- and
mid-level raptor movement today. A Sharp-shinned Hawk flew north below
eyelevel on the east side of the Ridge early in the morning. An adult
Turkey Vulture also migrated straight north to the east over Rooney Valley
a bit later. A juvenile Bald Eagle, with splotchy white underwings as well
as whitish, faded upperwings, passed north over the western ridges. The
last migrant was an unidentified buteo with a whitish underside (perhaps
brightened by the snow) that was spotted (while scanning contrails) as it
moved northeast, very, very high (HF4) over HawkWatch.
The local Red-tailed Hawks did not seem to be as active today; a few,
including the dark-morph, were seen nearby over Rooney Valley. Three local
adult Turkey Vultures headed south down Rooney Valley in the morning. One
adult Turkey Vulture was observed several times to come north up the
west-side valley, circle low, usually against the Ridge, then return south.
The local male American Kestrel spent the watch in Rooney Valley, hovering,
hunting, or perched on junipers at the base of the Ridge.

Non-raptor Observations:
A Canyon Wren was heard again but not until the afternoon. Also seen or
heard were Townsend's Solitaire, Black-billed Magpie, Western Meadowlark,
Spotted Towhee, Tree Swallow, Western Bluebird, American Robin, Common
Raven, Woodhouse's Scrub-Jay, Dark-eyed Junco, White-throated Swift,
American Crow, Black-capped Chickadee, and Northern Flicker. Seven Mule
Deer were seen near Cabrini.

Tomorrow, it is likely that the trail will still be mostly slick and sticky
mud as the snow finishes melting.

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
