Bart Berger of DenverMountainParks.org visited the site as we were departing. He had been a frequent visitor in the early days of Dinosaur Ridge. I will send to him the links to data. He wondered if we have seen trends. Weather: Cloudless and very windy in the morhing. 90% cloudy by 15:00 when we left Dinosaur Ridge. Temperature ranged from 3.0 deg to 11.5 deg celcius. Wind ranged from about 25 mph (code 5)to gusts over 40 mph (coce 7) Raptor Observations: Few of the local raptors were making their usual rounds. Few birds were migrating. Non-raptor Observations: The birds that are usually at the site were seldome seen due to the wind. A new commer, a Yellow-rumbed warbler, was seen by Francis Commercon, as were most of the rapters we recorded. ======================================================================== 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.
