   1. (Zool.) A pigeon of the genus Columba and various
      related genera. The species are numerous.
      [1913 Webster]

   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 Columba turtur or
         Turtur vulgaris; the ringdove, the largest of
         European species, is Columba 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 peace, innocence,
         gentleness, and affection; also, in art and in the
         Scriptures, the typical symbol of the Holy Ghost.
