Observers: Dale Campau , Dave Hill



Visitors:
Dave Hill and Dale Campau volunteered to observe this morning and stuck out the winds for a bit of time. Bill Rivers, Kathryn Mutz, Mark Chavez, and Aaron Shipe were also visiting the ridge this morning and helped spot birds while getting great looks and photos of the BW. It was a fun morning while it lasted. We had a total of 6 visitors up at the Hawk Watch today.

Weather:
Winds from the NW and W started out calm today but picked up as predicted. Clouds were scattered across the sky all morning. Humidity was low and fire danger was high all along the front range. At 1015 MST winds started consistently blowing at 40-50 km/h and were getting worse over the next 30 minutes, causing us to end the count at 1045 MST.

Raptor Observations:
We had a nice little push of migrants before the torrential winds settled in for the day, including three SS back to back! The highlight of the morning was an adult BW that came overhead and could be seen naked eye. Local RT were seen all morning using the winds to their advantage to hunt.

Non-raptor Observations:
We had a great variety of birds up at the ridge this morning including Pine Siskin (3), Lazuli Bunting (1), Rock Wren (1), Blue-gray Gnatcatcher (2), Stellar's Jay (1), Blue Jay (1), Yellow-rumped Warbler (4), and more of the usual suspects.

Predictions:
Sunny and warm with winds predicted to be moderate from the NE. We are hoping for more of the SS push that we got a hint of today.

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.
