A couple people stopped on the ridge, but visitor numbers have decreased since our Hawk Watch sign melted in the fire. Weather: The day started out great, with good cloud cover and a nice flow of migrants. After 0900 MST cloud cover increased even more and the flight stopped. Our usual search methods in a cloudy sky produced no migrants for several hours. The winds increased from the west after 1300 and became too strong to continue counting. The winds were highly variable and might explain the lack of migrant movement. Raptor Observations: We had a good push of migrating raptors near the ridge early, some were high but easily seen and some were eye level. Four local Turkey Vultures moved back and forth along the ridge. We had two good looks at Osprey. Non-raptor Observations: Passerines were fairly quiet. The rock wren was present, we saw a group of American White Pelican, and there were hundreds of white-throated swifts and swallows constantly moving across the sky. Predictions: The sun will rise in the east and set in the west. ======================================================================== 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 -- -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
