Flight

Some mammals such as flying squirrels are able to glide long distances, but bats are the only mammals that can really fly.

The shape of the wing varies in different species, and that shape gives clues about the way that particular bat flies. Long narrow wings, like those of the noctule, are designed for fast direct flight. This bat can fly long distances using less energy than bats with broader wings.

Short broad wings are designed for slower flight. They enable the bat to manoeuvre well, but as they use more energy, it will make short flights. The broad wings of the long-eared bat even enable it to hover as it takes insects from leaves.
