Mammal Home Page Animal Glossary Animal Resources Hanging in the Habitat Small Brown Bats have been sited in the Kellytown Habitat, an urban habitat in Charlottesville, Virginia. The bat roosts in trees, caves or in the eves of buildings. It likes dark, quiet places to hang out, especially in the fall and winter when it hibernates. To sleep, the bat hooks its feet onto tree branches or the eves of buildings and hangs upside down.
Bats like to eat insects.
They find food without using their sight. When they are flying, they send out squeaks that bounce of an object like a grasshopper. The squeaks echo back to the bat to tell it where the grasshopper is located. This process of sending out noises or using sonar is called echolocation . Bats can send out 10-200 squeaks per second, and can eat up to half their body weight in insects.
