Birds are the only vertebrates that have feathers. All birds are warm-blooded, and they lay eggs. Adaptations such as hollow bones enable most birds to fly, although there are flightless birds, including the ostrich. There are approximately 9,000 bird species in the world.

Reptiles are cold-blooded, usually egg-laying vertebrates (animals with backbones). Their skin is covered with scales or plates.
