How do bats sleep during the day?

Bats sleep during the day by hanging upside down in dark, sheltered locations such as caves, tree branches, or attics. Their feet are specially adapted to allow them to cling to surfaces while they rest. Bats’ muscles lock into place when they hang, so they do not have to use energy to maintain their grip. This behavior helps them avoid predators, like birds of prey, that are active during daylight hours. Bats are nocturnal creatures and are most active at night when they hunt insects or feed on nectar.
