No other mammal has wings and can fly. They are found throughout the world in both temperate and tropical climates.
Most bats are nocturnal and find their way by echolocation.
Sounds, usually above the range of human hearing, are emitted through the mouth or nose and are reflected back as echoes which enable the bat to avoid obstacles and locate prey. There are two major groups of bats - the Microchiroptera and the Megachiroptera. Most are insectivores, but some are specialized to eat fruit, fish, rodents, birds, reptiles, amphibians and even other bats. The vampire bats of tropical America are in the group and have become specialists at feeding exclusively on the blood of other vertebrates. Fruit Bats live in a variety of habitats from lowlands to mountain forests.
