The normal daytıme retreats of bats are the rooms of caves, but individuals commonly live in dry, dark rooms of buıldıngs.Males are usually solitary, but females, especially when they are young, gather in colonies.The bats dont hide ın crevices but, when not hibernating, hang from the open roof of caves or buildings where they can se, and escape from, any intruder. İn the dormant condition, which the bats assume when the aır temperature is low, the body temperature drops; and they cling with thumbs and toes to some vertical walls, with their ears closely coiled to conserve body heat.
