Visitors:
A CORA was flying close to the watch a little above eye level to the east and a hiker said How beautiful, and remarked on its shiny plumage. I told him that that's one of the identifying features compared to hawks. Just then the adult RT which patrols the Kestrel Channel landed on a tree downslope of us. I found it using my scope and invited him to look. He was thrilled.
Weather:
At 9:45 a.m. there was a mild haze around Denver and a minimal brown cloud just above the far horizon to the east but by 10:00 a.m. there was a prominent brown cloud most prominent over the NE horizon. The Soaring Forecast of the NWS had lift at 5 ft/sec with thermal height predicted at 4357 ft AGL which would make it 2557 ft above the watch i.e. a half mile above us, but only by 1:45 p.m., indicating that before that thermals would be even lower. This is caused by the subsidence inversion layer capping the height of the thermals. In addition the winds aloft were from the South, and together with no strong wind coming from the East that would not be any significant ridge lift over Lookout Mountain. For all these reasons I did not expect much of a migration today, and this was borne out, so on one hand that was disappointed but on the other hand I was happy that I was better understanding the meteorology and potential or not for a good migration at this site.
Raptor Observations:
The first migrant was only by 10:21 a.m. and was an RT. Golden Eagles: 1. At 10:48 a.m. an adult GE flew from the south over Lookout Mountain and went NE. 2. At 11:50 a.m. an adult GE was seen at the North end of Green Mountain which began its territorial display flight, so we lookrd for another raptor nearby, it dove and was lost. We then found it again and it migrated to the SSE at 11:59 a.m. 3. At 11:53 a.m. we saw an adult GE over the radomes of Buckley SFB below the far horizon, which migrated to the SE. Non-migrant raptors: RT 2.
Non-raptor Observations:
https://ebird.org/checklist/S409416148 A single paraglider at 1:39 p.m. had no lift at all, consistent with the Soaring Forecast.
Predictions:
Partly sunny, with a high near 68. West wind 6 to 10 mph, with gusts as high as 16 mph after 1:00 p.m. The winds aloft at 700 hPa, the height at which hawks would migrate at are going to be moderately strong c. 15 mph from the NW.
