Visitors:
Thank you to all of the volunteers today that helped look for migrants in between all of the local raptors. We saw 15 visitors at the ridge today, including three biologists with Jefferson County monitoring a rare (potentially very rare hybrid) plant species after the burn. We also saw another Jefferson County biologist out mapping the burn area. It’s incredible to see the work that is done after a wildfire and we are very grateful for the work they are doing.
Weather:
Temperatures were a bit lower today than the last few days giving us some nice relief. Cloud cover also helped with consistent clouds seen all day. Winds were variable and reached moderate speeds (15-20 mph) at times, coming predominantly from the W.
Raptor Observations:
We saw another slow day of migration today with 15 migrants counted, including a beautiful immature BE that went low in front of Mt Morrison. Non-migrant activity was high today with many TV (up to 4 at a time), three adult RT all seen throughout the afternoon flying together around the site, and an adult PG who we suspect is occupying the Red Rocks scrape.
Non-raptor Observations:
We were lucky enough to see the Chihuahuan Raven again this morning on the same power poles right next to the site. Pictures can be seen on eBird. We also saw a group over 50+ BBMA near the Mother Cabrini shrine. Other non-raptors include WTSW (30+), ROWR (1), SPTO (2), TOSO (2), BCCH (1), NOFL (1), AMRO (3), HOFI (3), CORA (6), and AMCR (2).
Predictions:
Snow is expected to move through the Rocky Mountains into the plains tomorrow into Saturday morning so we are hoping to catch some migrants moving in the morning to escape the storm.

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. 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)
