  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]
