Bird

Bird is a vertebrate of the class Aves. It is distinguished by a beak, feathers, and wings. This warm-blooded and egg-laying vertebrate is typically able to fly. Birds evolved probably during the Jurassic period spanning from 201.3 million years ago to around 145 million years ago from warm-blooded small dinosaurs. An aircraft, spacecraft, guided missile, and a satellite is also sometimes informally referred to as bird because of theirs being able to fly. A woman, a girl, or a specific kind of person is also informally referred to as a bird.
