Aves
n 1: (ornithology) the class of birds [synonym: {Aves}, {class
Aves}]

Aves \A"ves\, n. pl. [L., pl. of avis bird.] (Zool.)
The class of Vertebrata that includes the birds.
[1913 Webster]

Note: Aves, or birds, have a complete double circulation,
oviparous reproduction, front limbs peculiarly modified
as wings; and they bear feathers. All existing birds
have a horny beak, without teeth; but some Mesozoic
fossil birds (Odontornithes) had conical teeth inserted
in both jaws. The principal groups are: {Carinat[ae]},
including all existing flying birds; {Ratit[ae]},
including the ostrich and allies, the apteryx, and the
extinct moas; {Odontornithes}, or fossil birds with
teeth.
[1913 Webster]

Note: The ordinary birds are classified largely by the
structure of the beak and feet, which are in direct
relation to their habits. See {Beak}, {Bird},
{Odontonithes}.
[1913 Webster]
