Various hikers and bike riders, only a handful stopped to chat. One
special guest was Jane Haddock who did Hawk Count back in the late 90's
early 2000's. She plans to be back up on the Ridge to count again.

A beautiful, dry, dry day up on the Ridge. There was heavy smog emanating
from the Denver Basin, pushed up to the mountains by prevailing easterly
winds. The ceiling on this smog was about 200 feet, so did not impair
spotting birds. Light breezes all day.

Raptor Observations:
Seven local Red Tail Hawks were spotted. 4 on the east side of the Ridge
and Green Mountain. The other 3 were west over 1-70 and Mother Cabrini.
The migrators were flying very high, having to circle up to get a good wind
current, as Ridge height winds were low, and not accommodating to
low-energy migratory flying.

Non-raptor Observations:
Many, many more birds today than we saw last week. 5 Black billed Magpie;
5 American Robin; 2 House Finch (heard); 2 Northern Flicker; 3 Townsend's
Solitaire; 5 Chickadee (species); 2 Meadowlark; 9 American Crow; 2 Scrub
Jay; 2 Common Raven; 3 Mountain Bluebird; 20 Bushtit. Also one Cottontail
rabbit up by the station.

Tomorrow looks slightly cooler, with a 20% chance of precipitation---we can
only hope.

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
