Birds are an important part of our lives.
People have domesticated our feathered friends like chickens, turkeys, and mallard ducks, used birds as food, painted pictures and written stories about them, and used their feathers as ornaments. Their ability to fly has fascinated us for thousands of years. All birds, even water birds like penguins, have these lightweight structures. IN fact, birds are the only creatures in the world with feathers. Every bird, including flightless and semi-flightless birds like ostriches, penguins, and peacocks has wings.
