Visitors:
A hiker birder with binoculars and a paper list said he remembered me from a month ago. 3 birders from Westminster not with binoculars asked me a number of questions when I explained I was counting migrating raptors. One of them asserted that Red Tails don't migrate. I explained that they do and are replaced by others from the north so she thinks they don't. She also asserted that Ospreys were probably long gone, knowing that females leave as soon as the chicks are fledged. I told her I had seen one today. She said she had a Cooper's Hawk in her yard. Another asked me how many hours I counted a day and how long I was going to count until. I replied we will continue until the migration of raptors ends, I said I have counted until the end of the year as well as into the first 3 days in January in New York at the I-84 Overlook Hawk Watch.
Weather:
High pressure zone over Denver with the usual subsidence inversion layer causing haziness over Denver with a perfectly blue sky all day. The brown cloud was seen between the North and the Northeast along the horizon, but persisting to the NE even when Denver became clear by the 1:00 MDT hour. Winds as usual started in the SW and changed to the ESE. The winds aloft were from the SW. Lots of new snow on the 14ers to the West from the cold front a few days ago.
Raptor Observations:
First migrant was a CH at 10:09 a.m. MDT. Most of the migratory action was low along the Table Mountains and along the Kestrel Channel and only on the East end of Lookout Mountain while usually we have migrants over the middle to the West end of the mountain as well. Non-migrant raptors: GE 3, CH 1, RT 4. Monarch butterfly 1. Sandhill Crane 22 over Green Mountain, STJA 1, RECR 1, HAWO 1, BBMA 4, TOSO 1,,GHJU 1, CORA 10, AMCR 1, NOFL 1.
Non-raptor Observations:
11 paragliders, the ones starting at 12:30 PM had no lift, by 1:30 had moderate left and by 2:00 p.m. were high. The Soaring Forecast of the NWS predicted lift at 5 ft per second, height of thermals at 5,614 ft by 12:30 p.m., caused by the subsidence inversion layer.
Predictions:
Sunny, with a high near 76. West wind 5 to 7 mph becoming calm in the afternoon.
