Weather:
Another day with low winds predicted and they came out of the East, with mostly blue skies making it difficult to see migrants in the sky.

Raptor Observations:
I was still not feeling completely well after my COVID vaccine but Liza wanted to go to the top of Mount Zion, but there was a bicycle race in progress up Lookout Mountain Road, and when we got to the Windy Saddle Park parking lot, it was completely full with one car waiting to get in, probably support for the bicyclists, so we used the alternate site on Lookout Mountain Road toward Golden. Many of the raptors were seen through binoculars coming over the Northeast point of Mount Zion,going over the regular hawk watch site and continuing over the western end of Lookout Mountain, probably because of a strong ridge lift from the mild to moderate east winds hitting the ridge. Only 1 CH, the 1st bird of the day at 8:40 AM MST was seen to the east. We did not see any more there in spite of scanning high. I finally figured out that the air was too warm for thermals to develop, so the migrants were using the ridge lift over Mount Zion and Lookout Mountain. In fact, we saw 3 paragliders in the morning who could not get too high as they usually do as there appeared to be not much lift. In the afternoon when the wind became stronger in the last hour far, 3 paragliders again had the same problem; eventually 1 of them used ridge lift and got higher, but when he glided eastward he lost lift immediately and had to come back to the ridge to get higher. 1 of them flew only a little over the road making sharp turns at quite high-speeds. Non-migrant raptors: RT 4

Non-raptor Observations:
American Robin 1, Black-billed Magpie 1, Common Raven 4, Mountain Chickadee 1. Monarch butterfly 1.

Predictions:
Around the same as today. Monday should be interesting with strong NNE changing to NE wind at 10 mph with gusts to 20 mph. I'll be curious to see what raptors will fly, so that will be our next count day.
