Which bird sleeps in the air?
|
|
The swift sleeps, eats, and even mates in the air. It is perfectly built for flying. Its long, swept-back wings help it fly fast and high in the sky, where it hunts for insects. But its legs and feet are weak. It is hard for swifts to hop or walk. Some swifts spend almost all their lives flying.
