wind blowing form the north, so the Monarchs settles at sunset on the ocean side of the branches (south)
[Additional information contributed by observer, added by Journey North, 09/17/21]:
Roost formed early this year, to our surprise they were already forming and gathering early by end of august , early September. , monarchs are still there, each day there are more and more. On black pines before sunrise and flying in at sunset (amazing sight) for the night. 1st light, out and about all day. As soon as sun comes up and starts warming, they start to take off for the day.
This is on the outer ocean beach south shore long island New York. , they are flying around all day on cat tails, and pompass grasses . There are some native shrubs on bay side that flower but I do not know the name. They seem to like them. Next time, I will take a picture for sure.
Temps have been different high in the 70s one night to the low around 50
Wind direction each evening has been different. One night it is from the north, the next from south. Sept 16th it was around 20 kts.
Beach pine trees(black pine) are their favorite roosting tree, a line of 20 or more are covered at night on the protected side from the wind.
I have not tried to count. One small branch has a least 50 plus. Nearly impossible due to the volume. Mosquitos are insane as well right now. Can only stand for brief periods of time to get pictures because they are swarming around the area as well.
