Class Aves - Birds. 1  Waterproof skin covered in feathers. 2  Endothermic, warm blooded. 3  Hard shelled eggs that are waterproof (cleidoic - closed egg) 4  Beak or bill rather than teeth. 5  Bipedal (walk on two legs only) 6  Forelimbs developed into wings.
Birds are vertebrates with feathers, modified for flight and for active metabolism. Birds are a monophyletic lineage, evolved once from a common ancestor, and all birds are related through that common origin.
