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)
