Vulture \Vul"ture\ (?; 135), n. [OE. vultur, L. vultur: cf. OF.
   voltour, F. vautour.] (Zo["o]l.)
   Any one of numerous species of rapacious birds belonging to
   {Vultur}, {Cathartes}, {Catharista}, and various other genera
   of the family {Vulturid[ae]}.

   Note: In most of the species the head and neck are naked or
         nearly so. They feed chiefly on carrion. The condor,
         king vulture, turkey buzzard, and black vulture
         ({Catharista atrata}) are well known American species.
