Birds

Birds are animals that have feathers and that are born out of hard-shelled eggs. Some people think that what makes an animal a bird is its wings. Bats have wings. Flies have wings. Bats and flies are not birds. The truth is that it is the feathers who makes an animal a bird and not wings. All birds have feathers and birds are the only animals that do. The feathers on a bird's wings and tail overlap. Because they overlap, the feathers catch and hold the air. This helps the bird to fly, steer itself and land.
