Introduction
A bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals in the world naturally capable of flight. Around 1,000 bat species can be found worldwide. They make up a quarter of all mammal species, some bats consume insects others fruit and nectar. Some are carnivorous preying on small mammals, birds, lizards and frogs/fish. Some bat populations number in the millions, others are dangerously low or in decline.

Bats have evolved a highly sophisticated sense of hearing. They emit sounds that bounce off of objects in their path, sending echoes back to the bats. From these echoes, the bats can determine the size of objects, how far away they are, how fast they are traveling and even their texture, all in a split second.

Bats find shelter in caves, crevices, tree cavities and buildings. Some species are solitary while others form colonies of more than a million individuals. For their size, bats are the slowest reproducing mammals. At birth, a pup weighs up to 25 percent of its mother’s body weight, which is like a human mother giving birth to a 15kg baby. Offspring typically are cared for in maternity colonies, where females congregate to bear and raise the young. Male bats do not help to raise the pups.
