Number: 750

3 different trees with monarchs in the 100s roosting in them. Photo is of sugar maple; I counted over 150 in one quadrat of the tree, so I would estimate about 600 in the tree total.

The 600 in the tree I photographed was the most I saw in one tree. In the other two trees I would estimate 100 in one and 50 in the other. The tree with 100 monarchs was about 80 feet away from the sugar maple with 600. So that would total 750.
