Visitors:
21 visitors. We had a great group of birders in the morning, excited to see
the Broad-winged Hawks! Later in the day, we enjoyed greeting all the dogs
visiting the ridge.

Thank you to Paula Wegert, Dale Campau, Janet Peters, and Ryan Gannon for
volunteering today!


Weather:
The day started sunny with scattered clouds and a light wind from the SE.
Temperatures were moderate in the mid 60s to low 70s.

Mid-day, the winds shifted west and gained intensity to about 4 bft for a
brief period before returning to light E. Around the time the winds first
shifted, cloud cover became extensive for the remainder of the day. In the
final few hours, the winds returned to W at 4 bft.

Barometric pressure dropped throughout the day at a higher rate than
previous days.

Raptor Observations:
It was a good morning with most migrants in the first two hours. Our first
bird of the day, a juvenile Sharp-shinned Hawk, flew low overhead just as
we started the count.
Three Broad-winged Hawks were counted in the first hour - our highest day
total for the season so far. We also saw a juvenile Ferruginous Hawk fly by
at eye level, and a distant dark morph Swainson's Hawk. We also saw a young
Bald Eagle and Osprey on a line high over Mt. Morrison. While most activity
was on the west, a good number of birds also came on the east side, and
activity seemed to come in bursts.

After the first 2 hours, the birds slowed down drastically to just a few
per hour. In midday, many birds were observed overhead. In the late
afternoon we counted three American Kestrels.

Lots of territorial behavior was observed today, including RTs attacking a
GE and ravens attacking an RT. A local Cooper's Hawk was observed
performing aerial displays a few times throughout the day.

Non-raptor Observations:
White-throated Swift 50, Broad-tailed Hummingbird 3, Mourning Dove 2,
American White Pelican 3, Say's Phoebe 1, Black-billed Magpie 1, Common
Raven 3, Black-capped Chickadee 1, Barn Swallow 1, swalow sp. 5, Rock Wren
1, American Robin 1, Pine Siskin 1, Spotted Towhee 1, Western Meadowlark 1

Predictions:
Snow is in the forecast for tomorrow! Mixed precipitation is forecasted for
the morning pre-count, followed by snow until late afternoon. 1-3 inches of
accumulation is predicted, with the heaviest snow predicted between 10 am
to 2 pm MDT. Winds are predicted to be light to moderate NE with
temperatures in the low to mid 30s F.

Expect trails may be slippery, and traction devices may be helpful. We
intend to count if visibility is not too limited.

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk, Swainson's
hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk. Other
raptors we see include Golden and Bald Eagles, Northern harrier, Osprey,
Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned Hawks,
American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift, and
American White Pelican. Birders of any skill level are always welcome. The
hawk watch at Dinosaur Ridge is staffed by Hawk Counter(s) and volunteers
from March through early 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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.
