Official CounterRoger Rouch
Observers: Bill Wuerthele



Visitors:
None, through a few hardy runners were jogging on the trail.

Weather:
The first day of the 2014 season presented a pleasant winter scene of rime ice encrusted pines and juniper, gently falling snow, patchy fog, and low cloud ceiling. Temperatures hovered around 15 F with a light "refreshing" wind from the NE. The observation was terminated early due to poor visibility, adverse weather, and no raptor movement, with few signs of possible improvement.

Raptor Observations:
No raptors observed.

Non-raptor Observations:
2 Common Raven, 1 American Robin, 1 Townsend's Solitare.

Predictions:
Hopefully a break in the weather in the next day or two will release some pent up migration tendencies. Likely muddy or slippery trail conditions for the next day or days.

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.
