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.
Other kinds feed in heavy jungles or above a pond. Many bats eat as much as half their weight in food each night. They then rest in either their daytime roost or a different night roost. After digesting their meal, they may eat again. Sometime before dawn, they return to their daytime roost in order to sleep.
