A group of four stop by to ask about Hawk Watch. Jerry Stone helped spot birds and was especially good at finding local, perched Red-tailed Hawks. Weather: It was an overcast, cool day with a constant breeze from the northeast (100% cloud cover and 3B winds throughout most of the day). Temperature and humidity data were unavailable from the Rooney Road weather station. Raptor Observations: We observed five migrating raptors today: 1 Ferruginous Hawk and 4 Red-tailed hawks. One of the Red-tailed Hawks was a probable Harlan's, possibly the same bird seen yesterday by Dave Hill's group. We counted it as a migrant as it disappeared from view well beyond I-70, still heading north. Non-migrating raptors included a Prairie Falcon and a number of local Red-tailed Hawks. Non-raptor Observations: Non-raptors included: Towsend's Solitaires; Common Ravens; American Crows; Western Scrub-Jays; Black-billed Magpies; Bushtits; Mountain Bluebirds: Rock Pigeons; Dark-eyed Juncos; Canada Geese; a Northern Flicker; and an Eurasian Collared-Dove. ======================================================================== Report submitted by Rocky Mountain Bird Observatory (jeff.bi...@rmbo.org) 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.
