Historical Description

Birds (Aves) are a group of vertebrates. Like all terrestrial vertebrates (Tetrapoda), birds have two pairs of extremities, the front ones of which are transformed into wings. Plumage plays a major role in the overall appearance of birds: the body is covered in feathers. Most birds are able to fly. All flightless species have evolved from species that were originally able to fly. This applies, for example, to ratites, penguins and many island forms, such as the kiwi (New Zealand) and the stubby cormorant (Galapagos Islands). It is generally undisputed that birds come from the evolutionary line of reptiles. Crocodiles are considered to be their closest living relatives. Together, crocodiles and birds form the diapsid subgroup of the Archosauria.
