Two women came up to the station, one volunteers for Jeffco Open Space, who
mentioned seeing a grouse (sp.) at White Ranch. Both women knew about Hawk
Watch and were interested in knowing which hawks I'd seen migrate.

A gorgeous day up on the Ridge. Cloudless, low winds--it was already 16
degrees(C) when I got there. Perfect humidity, along with breezes kept it
from ever feeling hot.

Raptor Observations:
Migrators were sparse today, and were flying on both sides of the Ridge as
well as above. Some flew very low on the east side. The Broad-tailed Hawk
and Northern Harrier sailed directly overhead for a great view. Locals: 3
Red-tail Hawks; 2 TV's; and one Kestrel arrived late in the afternoon,
hovered, then landed on power line.

Non-raptor Observations:
A deer or elk met its demise on 1-70, right after the curve, by the sign
that warns to watch for them. A Cottontail rabbit hopped thru the station
twice today, numerous butterflies and grasshoppers. 4 American Crow; 4
Western Meadowlark; 3 Woodhouse's Scrub Jay; 5 House Finch; 1 Yellow-rumped
Warbler; 13 White-throated Swifts; 4 Black-billed Magpie; 2 Chickadee
(sp.); 4 Common Raven; 1 Spotted Towhee; 1 Broad-tailed Hummingbird; 1 Rock

Looks like another beautiful day tomorrow with a chance of p.m. rain. The
migration might be slowing as it's getting close to the end of the season.

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
