Observers: Karen Fernandez, Lisa Hope



Visitors:
Lisa Hope, a neighbor, joined 11:30 MST with binoculars and helped with spotting. She spotted one of the migrating Red-Tailedsâ€"not bad for a first day on the hill. We had 33 human visitors to the platform; only two asked about Hawkwatch.

Weather:
The day started out with a steady breeze from the east, creating an uplift on the east side of the ridge. Early raptors popped up into view from below eye level on the east side of the ridge. At 1:30 MST winds shifted to the south and then started gusting from the west up to 3 BFT the rest of the watch. High thin cloud cover ruled the day. Weather station: NOAA Clime for Lakewood.

Raptor Observations:
Migrating Raptors: The early hours of the watch were the busiest. 

Non Migrating Raptors: TUVU-5; RTHA-2.

Non-raptor Observations:
AMCR-15; TOSO-1; WTSW-12; CORA-10; MOCH-2; WOSC-1; DEJU-2.

Predictions:
Changes ahead again in the weather. Today was a lull day, so maybe a push ahead of the showers tomorrow.

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 of any skill level are always welcome.
HawkWatch at Dinosaur Ridge is generally staffed by volunteers 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
southwest end of lot to the 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.
(Distance: 0.56 miles, Elevation gain: 259 feet)
