Flying, in its true sense, is the ability to move through the air under your own power and has evolved in different groups of animals. Flight is a very energy demanding method of locomotion compared to walking. Some species, such as the peregrine falcon, are extraordinarily well adapted to flying. Others, like the albatross, look like they shouldn't be airborne at all, but are in fact fantastically efficient flyers. In spite of their name, flying squirrels and flying lizards don't fly, but glide.

Birds, bats and pterosaurs all evolved flight separately, a classic example of convergent evolution.
