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. They may
breed during late fall and winter, but embryonic development does not
begin until February in the North.
