Visitors:
5 hikers inquired regarding our activities there.
Weather:
Mostly clear, temperatures mid-60s to low 70s, winds from the SE, low humidity, minimal cloud cover, hazy visibility to 6 km because of forest fires in Canada, California, Wyoming and Western Colorado. By 10:00 a.m. MST there were small thermals forming to the West and the NNW.
Raptor Observations:
Fewer raptors seen today. The first migrant was an immature RT at 8:36 a.m. MST which circled repeatedly and slowly perhaps because of the SE winds, and eventually flew South. All of the other migrant raptors were seen mainly to the east, and south over Lookout Mountain. A younger woman hiker pointed out two naked eye birds for us over downtown Denver, binocular birds for us septuagenarians -- a CH with an SS. Non-migrant raptors: a beautiful juvenile GE with large white wing and tail patches which gradually move to the ne and eventually to the West. We showed this GE to a few hikers. RT 7. CH- one dropped over Lookout Mountain and another one just south of South Table Mountain. TV 2.
Non-raptor Observations:
Rock Wren 1, Steller's Jay 1, White-throated Swift 6, Spotted Towhee 2, Mountain Chickadee 3, Common Raven 1. When we counted in the past in NY State, we used the presence of TV aloft to indicate good thermals. Here in Denver, a single paraglider taking off below us indicated the same to us.
