Visitors:
There was a wonderful showing of volunteers on the ridge today! Thank you all! One of our weekend observers Laura Campbell began today! We are very excited to have her skill set on the ridge. You can find Laura observing on the Hawkwatch every Saturday..

Weather:
Overall clear day with light wind out of the E/NE. Light haze at the start of the count which cleared up around noon. Great day with wonderful clear overall flight lines.

Raptor Observations:
Today yielded a total of 14 migrants on the ridge! This is the best day so far this season. The days prior to today were both slow due to weather, yesterday being fogged in, so there was anticipation for all of those hunkered down migrants to make a bit of a push. 9 RT with the final bird of the day being a stunning adult dark morph making a close pass along the ridge. Both immature and adult GE and BE were spotted migrating along the W ridge. The adult FH was was spotted very far out along the western slope. Other highlights included a RT migrating over two local RT relatively low in the E, not even reacting to the locals, this bird had a few upper primaries with white on the wings, a very interesting looking individual that demonstrated clear migrant vs local RT behavior. Overall great day!

Non-raptor Observations:
Today we observed a nice N/NW movement of Mountain Bluebirds in the first 2 hours of the count along with 2 NE bound Pine Siskin. There was considerable movement of crows and a few ravens in the afternoon directly east of the ridge.

Predictions:
Tomorrow similar conditions are expected. Another possibility for a good push of migrant action!

Site Description
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Hawk watchers may
see 17 species of migrating raptors; and it is an excellent site to see rare
dark morph buteos including Broad-winged hawk, Swainson’s hawk, Ferruginous
hawk, Rough-legged hawk and Red-tailed Hawk. Other raptors we see include Golden
and Bald Eagles, Northern harrier, Osprey, Peregrine Falcons, Prairie Falcons,
Cooper's and Sharp-shinned Hawks, American Kestrels, Merlin, and Turkey
Vultures. American Goshawk is uncommon but also counted each season. Non-raptor
species include Rock Wren, Bushtit, Western Bluebird, Sandhill Crane,
White-throated Swift, American White Pelican, and Dusky Grouse. Birders of any
skill level are always welcome. The hawk watch at Dinosaur Ridge is staffed by
Hawk Counter(s) and volunteers from March through early 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 hawk watch signs from the
southwest end of the parking lot to the hawk watch 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, and walk to
the flat area at the crest of the ridge. (Distance: 0.56 miles, Elevation gain:
259 feet)
