Late in the day a couple from Greely already interested in raptors got to witness a few migrators passing by. An avid birder, Janet Jamison had heard about the HawkWatch through RMBO. She helped to spot birds for a couple of hours. Janet is interested in finding out more about the HawkWatch and perhaps helping out next season. Weather: A comparatively cool day with temperatures maxing out at about 10C and a moderate but consistent breeze out of the NE. The day started out with a very high, very thin cloud cover. Mid-level clouds continued to increase over the day ending with about 85% coverage at days end. Raptor Observations: As we near the end of the season a pretty good day with 29 migrating birds. Most activity occurred during mid-morning and in the last 2 hours of the day. Many of the birds were close in or easily viewable with binoculars passing in a determined fashion to the north. Local birds were occasionally seen along the west ridge, unusual, very little migratory activity was noted there. Local raptors included RTHA, COHA, SSHA, AMKE and TUVU. Non-raptor Observations: A number of small flocks of Yellow-rumped Warblers in apparent migration passed over the station. Four Ruby-crowned Kinglets provided some nice views. Common Ravens playing in the wind provided a source of entertainment throughout much of the day. Good numbers of White-throated Swifts also enjoyed the wind, making high speed passes over, around and through the station. Species seen or heard included: Black-billed Magpie, Western Meadowlark, Spotted Towhee, Mountain Chickadee, Black-capped Chickadee, Yellow-rumped Warbler, Broad-tailed Hummingbird, Townsend's Solitaire, White-throated Swift, Violet-green Swallow, Barn Swallow and Blue-grey Gnatcatcher. Predictions: Nearing the end of the season, diminishing counts would seem logical. But with all the wet weather this spring, the birds may have other plans. ======================================================================== 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.
