Visitors:
5 hikers asked us what we were looking for, including a young woman who had just moved here from New Orleans who asked whether we were bird watching, and when we explained she said that before she had the two children with her she had worked for the CCC, but hawk watching was out of her experience.
Weather:
A weak cold front had gone through yesterday without any rain and a high pressure zone supervened with a subsidence inversion layer causing haziness from just East of the Table Mountains all the way to the Eastern horizon. There was a perfectly blue sky all day, and this is going to continue all week except for Tuesday when there's going to be about 40% cloud cover.
Raptor Observations:
The first Raptor was an adult GE at 9:19 a.m. MDT in the gap between Green Mountain and Lookout low but it did not migrate. Instead of a 'noon lull' we had an 'early morning lull' because of the perfectly blue sky, very few hawks we could see migrating compared to yesterday, presumably they went high early. The Soaring Forecast of the NWS predicted lift at 8 ft per second but the height of thermals was only 7392 ft AGL at 11:00 a.m., however the Hawks could have used a ridge lift extending all the way from northern Colorado along the Front Range of the Rockies. We did scan straight up with binoculars but couldn't see any migrants - perhaps too high for binocular detection.
Non-raptor Observations:
https://ebird.org/checklist/S399292730 10 paragliders, the ones starting at 10:45 a.m. MDT had no lift, only 1 got above our elevation, by 11:30 a.m. 2 had moderate lift only.
Predictions:
Sunny, with a high near 86. West wind 5 to 9 mph becoming calm in the afternoon. Winds could gust as high as 15 mph. The winds Aloft at 700 hectopascals was expected to be from the West to North and then from the NE.
