   Mound bird. (Zool.) See moundbird in the vocabulary.

   Mound builders (Ethnol.), the tribe, or tribes, of North
      American aborigines who built, in former times, extensive
      mounds of earth, esp. in the valleys of the Mississippi
      and Ohio Rivers. Formerly they were supposed to have
      preceded the Indians, but later investigations go to show
      that they were, in general, identical with the tribes that
      occupied the country when discovered by Europeans.

   Mound maker (Zool.), any one of the megapodes. See also
      moundbird in the vocabulary.

   Shell mound, a mound of refuse shells, collected by
