Birds

by Slim Goodbody

Maybe people keep birds as pets because they can do what humans can only dream about, which is to fly. Readers explore how a bird's special bones, air sacs, muscles, and feathers make this feat possible. They'll discover why these winged creatures have two stomachs and how they can sleep without falling off branches.
