Wikipedia:Good articles/Bird

Birds are a group of animals with backbones. Birds are the only dinosaurs that survived and are part of the theropod group of dinosaurs. The word for "bird-like" is avian. Birds are warm blooded. Their feathers help prevent loss of body heat. Modern birds do not have teeth. They have beaked jaws. Birds have wings. The wings develop differently in different species. In general, birds inherit their behaviour almost entirely.
