Taxon:Aves

Aves (Linnaeus, 1758) or birds are two-legged, two-winged (four limbs total), feather-covered (except usually the legs, feet, and beak, and in vultures, the head), warm-blooded chordates. They have a beak.

NOTE TO TAXONOMISTS: The taxonomy of birds is fairly abstract, so if a creature does not perfectly fit the commonly accepted idea of what constitutes a bird in the strictest sense (for instance, has four wings or has arms instead of wings, or the eyes are on eyestalks), it should be placed in the less strict and better sorted class Avoidia. This will help keep the system as simple as possible to use.
