Birds

Birds are warm-blooded animals with feathers, a beak and two wings. All birds lay eggs with hard shells, and most can fly. Their bones are light and partly hollow. Birds that cannot fly, such as the ostrich and the penguins, use their strength for running or swimming instead. Birds are the living descendants of dinosaurs.
