   butor; of unknown origin.] (Zo["o]l.)
   A wading bird of the genus {Botaurus}, allied to the herons,

         {stake-driver} and {meadow hen}. See {Stake-driver}.

   Note: The name is applied to other related birds, as the
         {least bittern} ({Ardetta exilis}), and the {sun
         bittern}.

Bittern \Bit"tern\, n. [From {Bitter}, a.]

      magnesium which it contains.

      used by fraudulent brewers in adulterating beer. --Cooley.
