Dove \Dove\, n. [OE. dove, duve, douve, AS. d?fe; akin to OS.

   1. (Zo["o]l.) A pigeon of the genus {Columba} and various
      related genera. The species are numerous.

   Note: The domestic dove, including the varieties called
         {fantails}, {tumblers}, {carrier pigeons}, etc., was
         derived from the {rock pigeon} ({Columba livia}) of
         Europe and Asia; the {turtledove} of Europe, celebrated
         for its sweet, plaintive note, is {C. turtur} or
         {Turtur vulgaris}; the {ringdove}, the largest of
         European species, is {C. palumbus}; the {Carolina
         dove}, or {Mourning dove}, is {Zenaidura macroura}; the
         {sea dove} is the little auk ({Mergulus alle} or {Alle
         alle}). See {Turtledove}, {Ground dove}, and {Rock
         pigeon}. The dove is a symbol of innocence, gentleness,
         and affection; also, in art and in the Scriptures, the
         typical symbol of the Holy Ghost.
