How do bats’ wings differ from birds’ wings?

Only birds, insects and bats can truly fly, although quite a few other animals can glide through the air. Birds’ bodies are covered in feathers, and on their wings are feathers called flight feathers which are specially shaped to allow the bird to fly gracefully; these feathers are often coloured to help conceal the bird from its enemies or help it attract others of its own kind. Bats’ wings are different because instead of feathers, the wing is made of thin skin which stretches across the body and is supported by the bones of the arms and legs. If you look at the picture of the bat on the right, you can see how the wing is supported. The long bones which support the wing are really its fingers, but of course they are much longer than our own fingers. The short bone which sticks out at the top (the toilet claw) is its thumb.
