"BATS"

WHEN most other creatures return to their Holmes for the night, bats take to the air. BATS are the only mammals capable of flight. They are nighttime creatures with leather-like wings that enable them to swoop and glide  through the darkness catching moths and other airbone insects. Although most bats are insectivores (insect eaters), some feed on fruit, nectar, pollen, fish, small mammals, and reptiles. Most bats give birth to one or two young each tear. The young are left in a nursery roost, clustered together for warmth, while the mother flies off tô feed. There are nearly    1, 000 different kinds of bats, including red bats, brown bats, and dog-faced bats. They make up one quarter of all mammal species, yet few people have ever seen one. Today, Manu kinds of bats are becoming rare as their roosts are destroyed and their feeding areas are taken over for farming and building. In Britain, all bats and their roosts are protected by law.
