Observers: | Dave Erickson, Gary Rossmiller, Janet Peters, Marianne Erickson, Sammy Korengut |
Visitors:We had 12 visitors total today, and I had the help ofJanet Peters, Gary
Rossmiller, Sammy Korengut, and Marianne & Dave Erickson for todays count.
Weather:Today was a pleasant spring day with a high of 10 degrees Celsius and sunny
conditions all day, a great change from yesterday. Wind was mild for most
of the day, with a slight chill in the morning. Winds were predicted to be
variable but instead were consistently coming from the NE. A haze was
present and limiting visibility slightly for most of the day, lifting
towards the end of the count.
Raptor Observations:We had another great early season day with 11 raptors counted including RT
(9), ML (1), and PR (1). We also had local GE, BE, and what we believe to
be the nesting RT pair that was here last year. The flight was high today,
with a westerly flight line in the morning. The flight line eventually
shifted to overhead, but birds were still migrating at high altitudes.
Non-raptor Observations:Non-raptor species seen today include WOSJ (2), HAWO (1), NOFL (1), AMCR
(4), CORA (4), BCCH (2), TOSO (5), AMRO (3), and our first MOBL (5) of the
season. We also spotted four elk just along the horizon right of the Mother
Cabrini figure.
Predictions:Another sunny day that will likely start out a bit brisk. Winds may have a
westerly component tomorrow, which often brings a slow flight to Dinosaur
Ridge. Cloud cover is variable but predicted to be sparse for most of the
day. We are yet again hoping for a nice early season 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)
