A busy Colorado morning with almost all hikers and families (very few
bikers). No elk or deer spotted. A trail runner who spent some time
observing with us had some curiousity and stated he talked with HawkWatch
members during the on-the-hill orientation this year. New Jeffco open space
ranger appeared but was not conversational.

Warm, sunny and dry with a steady breeze for the duration. "Sunshine" fire
west of Boulder did not seem to impact visibility. Criss-crossing aircraft
con trails all day helped share sightings. Winds shifted to the west and
south at noon, seemed to move some fliers from west to overhead, but
shifted back to ESE soon after. Most sightings today were over western
ridges or very high directly above.

Raptor Observations:
Overall, a neck aching, arm numbing day; we needed a Lazyboy on the ridge!
Back to reality: A diffifcult day for raptor-at-elevation identification.
All day, raptors tended to ride thermals starting south of the ridge, a few
then dropped down to low west of ridge, ride another up in front of Two
Pines and then spiral north over Apex and Lookout towards Boulder. Others
disappeared above 10x binoc limit. Two wide-area local RTHA appeared
several times AM & PM circling over Green Mountain. Four likely BAEA (ID:
shape of wing) circled high over Mt Morrison mid AM but ID was compromised
as they reached the limit of 10x binocs and we did not see them proceed
north of Mount Morrison; not counted. Either a Rough-Legged Hawk or
Ferugginous Hawk appeared at south end of ridge (late AM mst), rode up to
limit of binocs then northwest to Power Lines and then, unfortunately,
behind horizon at Subpeak, although consistently moving northward; counted
as Unkown Buteo. All day we observed several red-tailed hawks of "migratory
status undetermined" (they may be locals of a wider area, but they were not
the nearby locals we know) rise beyond sight above us and their movement
from there was not perceptible.

Non-raptor Observations:
Non-Raptors seen or heard (and reported on eBird): Northern Flicker (2),
Woodhouse's Scrub-Jay (2), Black-billed Magpie (5), American Crow (13),
Common Raven (5), Black-capped Chickadee (1), Bushtit (1), Townsend's
Solitaire (1), American Robin (2), Dark-eyed Junco (1), Western Meadowlark
(1) and House Finch (1). No observations of elk or deer today.

Scope recommended, as noted in previous submissions. What about setting up
a loaner to check out at the Dinosaur Ridge Discover Center? Their hours
through April are Monday through Saturday 9:00 AM to 4:00 PM and Sunday
10:00 AM to 4:00 PM, then open till 5:00 PM in May. Not ideal but could
make it work.

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
