It was a slow day for visitors as well, with 14 visitors seen at the ridge. One couple spent a few minutes asking questions and reading the count board. Weather: It was a hot day today with cloud cover on and off all day, until rain clouds could be seen in the area as we were hiking out. Winds were variable but from the NE for a good chunk of the day, only reaching moderate speeds in a few gusts in the late afternoon. Raptor Observations: Migration was slow today with 10 total migrants including 2 more FH. We continue to expect them to be done migrating and they continue to prove us wrong! Local raptor activity was very high today with 7 non-migrant TV seen at once and three adult RT. Non-raptor Observations: 2 ROPI were at the site as we got to the ridge this morning. We also continue to see the regular passerines including BGGN, WTST, VGSW, and SPTO. Corvid activity has decreased since the beginning of the season, presumably because they have separated to breed. Predictions: More sun with partial cloud cover expected tomorrow and winds from the E. We are still hoping to get more BW, SW, and are on high alert for migrating MK. ======================================================================== 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 Count data submitted via Dunkadoo - Project info at: https://dunkadoo.org/explore/denver-field-ornithologists/dinosaur-ridge-spring-2023 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.
