Many are beginning to roost in pecan trees above the blue mist patch. Seeing more each night and morning.

Monarchs began roosting on Friday. Until then, there had been many at a time, but I didn't see them roost. Am guessing they left Saturday morning. There was much activity Saturday morning. Then tapered off. Then we purposefully sat under the pecan trees about 5:00PM.

My count is by several methods. I took a slo-mo video and scanned the blue mist. Then counted a couple of the frames. Also, sat and observed the blue mists for five minutes before counting. Counted 18. Then took photos of several roosts in different pecans and counted those = 60, easily verified. Then walked to sunflowers. Sat and observed = 6. Walked to a different area of pecans and took another photo to count that roost = 30.

Blue mist is directly below one roost site of pecans. Second roost site is not near any nectar source, but next to a pond. Third pecan tree is near sunflowers.

Shielded from wind. and if there is a wind, they roost on the downwind side of the tree. Right now, we are breezy more than windy.
