A bird is an animal with wings, feathers, and two legs. Birds, from chickens to crows, are also warm-blooded and lay eggs.

Most birds can fly using their wings, and when you visit the coast you'll see various sea birds like gulls, terns, and cormorants. You can use the word bird as a verb meaning "to observe birds as a hobby," and in some places, particularly Britain, it's also a noun meaning "young woman." Bird is an Old English word, an unusual form of bridd, "young bird or fledgling," from an unknown origin.
