Habitat and Habits
There are two primary types of habitats for many bats: hibernation sites used during the winter (e.g., caves, mines) and roosting sites for reproduction (e.g., tree cavities) during the summer.
Reproduction and Care of the Young
Breeding takes place during the late summer and early fall during a behavioral phenomenon known as “swarming.” At this time, large numbers of bats visit and congregate in a succession of caves just prior to hibernation. Although sperm is transferred to the female during copulation occurring in the fall, ovulation and fertilization of the egg are delayed until the females arouse from hibernation the following spring.
