But a number of species do not walk at all. They use their legs simply to hang from their roost. Each foot has five toes with semicircular pointed claws that enable the animal to hang securely from twigs and rocks. Many species of bats live in colonies that may have thousands or even millions of members. Others live alone or in small groups.
Most bats spend the day sleeping in their roost.
They also may groom their fur and wings or tend their young during the day. About an hour before dusk, bats start to move around or take short flights. At dusk, they begin to fly from their roost and head for their feeding grounds. Many species eat insects, and each species seeks its own kind of feeding area. Some bats feed in open areas.
