Habits

They leave their daytime retreat at dusk and return to the roosting site just before dawn. Colonial. They feed on insects on the wing near the water or forests with an erratic flight. In the North, most migrate South in the fall and go into hibernation in a cave or other suitable retreat. Although they become torpid, they do not go into a deep sleep.
