Visitors:Typical Saturday with people enjoying the nice weather.
Weather:Day started sunny and with little to no wind but throughout the day the
wind picked up to 10mph intermittently and cloud cover become 90 to 100%.
Raptor Observations:Many raptors early in the day and all seemed to be in a serious hurry!
Lots of continuous flapping seen with some of the Red Tails as well as a
Bald eagle that at first glance seemed to be corvids. In late morning we
got some great aerial territorial battles that made for easy counting with
who lives here and who's passing through.
Non-raptor Observations:Lots of Chickadees, robins, and Townsend's Solitaires and a handful of
Juncos. We did see in the distance what looked like a flock of Bluebirds
but couldn't confidently ID them.
Predictions:If it's a trend with the nicer weather, start early. We had 6 birds in the
first hour and all were heading north.

Dinosaur Ridge information may be found at:
http://www.rmbo.org/Site DescriptionDinosaur 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.
