Visitors:
Big thanks to Carol, Steve, Steve, Susan, Ajit, and Liza for helping spot and ID birds today. Ajit and Liza are headed back to NY but we look forward to seeing them again next season once they move to CO. Trail activity was very busy with runners and bikers, but we only had 28 visitors to the Hawk Watch today.

Weather:
Pleasant morning with minimal cloud cover. Cloud cover was minimal throughout the day, but as the day went on the temperature increased reaching 14 C with strong sun. A light haze settled in early afternoon. Winds were variable for much of the day.

Raptor Observations:
Birds stayed high and over the western mountains for most of the day but we had another great day of migration. FEHA are still being seen, with two dark morphs seen today. SSHA, COHA, MERL and AMKE are picking up in numbers.

Non-raptor Observations:
White-throated swifts (60) were seen high in the west valley throughout the day. The first Tree Swallow and first Western Meadowlark were seen today. Corvid activity was high, and many times Common Ravens could be seen harassing migrating raptors.

Predictions:
Heavy cloud cover with probable light rain showers. Winds are variable.

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.
