Observers: Karen Fernandez



Visitors:
We had a total of 17 visitors on the platform. Two were conversational about HawkWatch.

Weather:
Brilliant blue sky and bright light off the snow. Cool temps and slight SE breeze. Good visibility. Trail was frozen mud on the way up; slush and a little muddy on the way down. 

Started with Weather Underground at Green Mountain (Edgemont), but problems with that PWS. So after the first hour used NOAA at Lakewood.

Raptor Observations:
Migrating Raptors: All four migrating RTHA climbed high above Mt Morrison and points north, then straight disappeared northwest at Bare Slope. 
Non-Migrating Raptors: 
Local RTHA on a pole near the Thunder Mountain race track, and then later guided a migrating RTHA northward from Power Lines to Cabrini. 

Two other RTHA appeared above Mt Morrison, circled up towards the NW, and disappeared above West Ridge. These two were not counted. 

Two local RTHA circled and interacted over Two Pines.

Non-raptor Observations:
Five deer grazing at the base of the west facing slope near Hwy 93.
 
AMCR - 4. 
CORA - 2. 
TOSO - 2 in trees next to the platform. 
WOSC - 2 on the platform. 
HOFI - 1. 
MOCH - 2. 
BUSH - ~40 came flowing through the junipers on the platform.

Predictions:
Not bad count and conditions for the first day of the 2021 DinoHawk season.

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.
