Observation start time: 07:30:00
Observation end time: 14:00:00
Total observation time: 6.5 hours

Official Counter: Heidi Hayes, Roger Rouch

Observers: Heidi Hayes, Joel Chapa, Mitchell Blystone, Rob Reilly

Visitors:
A few curious hikers.


Weather:
In spite of moderate temperatures in the mid 30's and 40's, a brisk
northeastern wind around 3 Bft, a mostly cloudy day, and higher humidity
gave a chill to the air. Moderate atmospheric haze.

Raptor Observations:
The flight pattern today included many raptors close to the ridge above and
below eye level, apparently using ridge lift and wind rather than thermals.
Some made northern flight seem effortless against a northern wind. Flat
light and some haze lead to many identifications by silhouette and flight
characteristics. Local falcons were sighted more than once and a Peregrine
and Prairie Falcon gave every indication of migrating and were added to the
tally. Local Red-tailed were active often below eye level. Also a local
Cooper's and a few local Turkey Vultures.

Non-raptor Observations:
Songbirds travelling in small groups of 2s,3s or more were common
especially in the early hours. Some were speculated as Yellow-rumped
Warblers and two Yellow-rumped landed in the dead pine near the platform.
Some unk. swallows and others not identified. Also seen or heard were
Broad-tailed Hummingbird, Western Meadow Lark, American Robin, Common
Raven, Woodhouse's Scrubjay, White-throated Swift,Black-Billed Magpie, Rock
Pigeon, Morning Dove, chickadee, and Dark-eyed Junco.

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.
