Weather: The forecast called for 16 mph winds in the afternoon and a chance of rain after 2 PM. We did have a drizzle in the 1-2 PM MST as well as at the beginning of the 4 PM hour, which were both short-lived. The winds were only represented by very brief but very strong gusts. Winds mainly from the E>ENE, cloud cover initially only in the West but gradually covered the South and overhead which helped us actually see raptors, mild haziness. Raptor Observations: The 1st migrant was an adult SH at 8:31 AM. Non-migrant raptors: adult SH which dropped into the valley to the west presumably to hunt, immature CH did the same on the east, in last 0.5 hours an OS flew south low over the watch, a PG, RT 4 - 1 with a full crop, TV 4. Non-raptor Observations: Around 125 Tree Swallow suddenly at 3:25 PM MST, Blue-gray Gnatcatcher 1, Western Kingbird 1, Western Meadowlark, Woodhouse's Scrub-Jay 2, White-throated Swift 4, Broad-tailed Hummingbird heard 3 times, Common Raven 2. I was delighted to see Carol at the watch who had gotten there just before I did – she was subbing for Natalie who was taken ill. Speedy recovery to Natalie. Carol was very helpful in spotting and identifying raptors and on questioning her giving me ID hints. In the afternoon Shannon found a CH behind me as soon as she got to the watch, and she and Martha were helpful spotting raptors. Predictions: The weather forecast is similar to today but with a risk of rain only after the watch end, and so migrants presumably should be similar to today. ======================================================================== Report submitted by DAVID HILL () Dinosaur Ridge - Denver Field Ornithologists information may be found at: http://www.dfobirds.org More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123 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.

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.
