Observers:

Visitors:
6 visitors stopped by the ridge today to look for birds, including one
visitor celebrating a birthday! We had multiple visitors that came up to
the Hawk Watch for their first time after hearing about it through DFO or
eBird. Yay!




Weather:
Today was warmer than it has been the last few days but the winds continue!
Within an hour of the count starting winds picked up from the W. Winds
stayed strong for most of the morning, took a break in the afternoon, and
picked back up at the end of the day causing the count to be ended early.

Raptor Observations:
West winds typically bring little to no migration activity but today was a
nice exception. Birds moved along the E lines over Green Mountain
predominantly, with the common W lines being empty. Many birds stayed low
in flight to presumably avoid the winds. Highlights of the day include a
picture perfect Harlan's Red-tailed Hawk that came low along the ridge, our
first Golden Eagle migrant (finally), our first Turkey Vulture of the
season, and our first migrating Northern Harrier! While we didn't break
into the 20s+ yet for migrants, we had some great diversity today.

Local Red-tailed Hawks, Golden Eagles, and Bald Eagles could be seen almost
constantly using the wind to hunt and perform courtship displays.

Common Ravens were also up moving almost constantly all day.

Non-raptor Observations:
Say's Phoebe 1, Woodhouse's Scrub Jay 1, Common Raven 5, Black-capped
Chickadee 2, American Bushtit 5, Mountain Bluebird 4, Western Bluebird 4,
Townsend's Solitaire 1, American Robin 24, Dark-eyed Junco 1, Spotted
Towhee 2, Western Meadowlark 1

Predictions:
Temperatures continue to rise tomorrow and winds will hopefully relax a
bit. Maybe tomorrow will be our first 20+ bird day?

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.
(Distance: 0.56 miles, Elevation gain: 259 feet)
