Weather.gov predicted chilly weather in the low 40s F with NW winds at 15 mph. Earth.nullschool.net showed a very strong band of West winds to the north of Denver near the Wyoming – Colorado border and very much stronger than that at the hawk watch location – and we had quite ferocious winds, probably caused by a "fall wind" (from my limited but increasing knowledge of local meteorology) which would push any potential migrants coming south along the Front Range instead far to the East of Denver to the plains area around the Denver Convergence Vorticity Zone. Https://glossary.ametsoc.org/wiki/Fall_wind Raptor Observations: The only raptors seen were up to 3 local RT which were gratefully observed by us – overhead, and a pair over Green Mountain. Schmuel "Sammy" Korengut came up to help us and I told him that only a true hawk watcher would come out in such conditions with the prospect of seeing none to only a few migrant hawks. Non-raptor Observations: Townsend's Solitaire 3, Common Raven 2, American 3, Woodhouse's Scrub-Jay 1. ======================================================================== 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. 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 small signs from the southwest end of lot to the hawkwatch 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, head through the gate, and walk to the clearly-visible, flat area at the crest of the ridge.
