Weather: Cool with temperatures rising from 1C to 6C. Moderate winds ranging from 2 to 4 Bft. with some stronger gusts. Mostly sunny. Raptor Observations: Migrating raptors were mostly along Dino Ridge, but no strong trend for time of day. A Rough-legged came from the Green Mountain direction, perched on the power poles to the east of the ridge and moved on after being harassed by a local Red-tailed Hawk. We got some fun photos of this which will be posted later. Local raptors observed were Golden Eagle, Prairie Falcon, and Red-tailed Hawk. Non-raptor Observations: Seen or heard were White-throated Swift, Mountain Chickadee, Western Scrub-Jay, Black-billed Magpie, Western Meadowlark, Bushtits, Common Raven, Townsend's Solitaire, Mountain Bluebird, Western Bluebird, Northern Flicker, and American Robin. Mountain Bluebirds entertained observers throughout the day as they foraged in the bush to the east of the ridge and made several fly-bys. ======================================================================== Report submitted by Rocky Mountain Bird Observatory ([email protected]) Dinosaur Ridge information may be found at: http://www.rmbo.org/ Site Description: Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is the best place in the world to see migrating Ferruginous Hawks. Dinosaur Ridge may be the best place in the country to see the rare dark morph of the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular. Non-raptor species include Rock Wren, and sometimes Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or Dusky Grouse. Birders are always welcome. The hawkwatch is generally staffed by volunteers from the Rocky Mountain Bird Observatory from about 9 AM to around 4 PM from the first week of March to the first week of May. 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 south side of lot to 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. -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
