Visitors:We had 6 visitors at the site today and 7 observers that helped spot and
count raptors today, so thank you all!
Weather:Today started out with dense cloud cover but that quickly dissipated
revealing more sun than we expected. The clouds were present but variable
throughout the day, significantly impacting the temperature as the sun was
covered. There was a thick haze that was present all day, making visibility
worse as the day went on. Winds were mainly from the NE blowing at mild
speeds.
Raptor Observations:Migrant raptors were seen mostly overhead or in the western valley today,
with some being at the limit of an unaided eye. Highlights today included a
close sub-adult GE, and three FH that came overhead throughout the day. The
flight slowed down at the end of the day with our last migrant counted in
the 1300 hour. We also observed three local RT today, including our pair
that we have seen most days this season, and one local GE over the western
ridge.
Non-raptor Observations:The MOBLs continued to move through today with 13 counted, and a suspected
~20 over Green Mountain that were tricky to ID. We also saw SCJA (2), DEJU
(8), HOFI (2), CORA (9), TOSO (3), and AMRO (3) at the count site today. 15
Elk were seen just north of the Mother Cabrini statue.
Predictions:Tomorrow should be sunny with limited cloud cover and high spring
temperatures, but we have winds of 30-40 mph on the radar, which may limit
our day.

Site DescriptionDinosaur 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. Northern Goshawk is uncommon but also counted each season. Non-raptor
species include Rock Wren, Bushtit, Western Bluebird, Sandhill Crane,
White-throated Swift, American White Pelican, and Dusky Grouse. Birders of any
skill level are always welcome. The hawk watch at Dinosaur Ridge is staffed by a
Hawk Counter and volunteers from 9:30 AM to 5:30 PM from March 1st to May 14th,
weather permitting.
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)
