Visitors:
A few hikers came up into the site and asked what we doing, none of them expressed a serious internest.

Weather:
A nice day, temperatures in the low 80's, light breeze out of the east all day long. High cloud cover provided very good conditions for observation.

Raptor Observations:
A majority of the migrating raptors observed today moved steadily, quickly and directly north. Like they were late for the party and knew it. Most of the local RT and TV action occured along the west ridge today. A "committee" of as many as nine TVs roamed the length of the west ridge. Two pair of RTs were observed in a limited altercation. A local Swainson's Hawk was hunting the west slope of Green Mountain from high in the valley as it kited along to the south. (Either seen twice or two birds.)

Non-raptor Observations:
Highlight of the day was easily the Lewis's Woodpecker that flew thorugh the station at about 9:20 AM Bird Time. It landed on the bare limbs of the pine at the south end of the visible ridge, then moving to the adjacent snag to the east. We were able to view it through the scope for several minutes. A small young rattlesnake showed up in the rocks right in the middle of our things near the central highpoint of the station. A second small rattlesnake was seen on the trail near the parking lot on our way down. Non-raptors, the usual suspects, Blue-gray Gnatcatchers, Spotted Towees, White-throated Swifts, Scrub Jays, Blue Jay, Western Meadowlark, American Robin, Great Blue Heron, Broad-tailed Hummingbird, Barn Swallow, Common Raven.

Predictions:
The morning could be much like today with a few migrating raptors moving through. Thunderstorms are possible in the afternoon, give lightning the respect it's due, the site is very exposed.

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 the Rocky Mountain Bird
Observatory from about 9 AM to around 4 PM from the first week of March to the
first week of May.

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.
