Brush turkey \Brush" tur`key\ (Zo["o]l.)
   A large, edible, gregarious bird of Australia ({Talegalla
   Lathami}) of the family {Megapodid[ae]}. Also applied to
   several allied species of New Guinea.

   Note: The brush turkeys live in the ``brush,'' and construct
         a common nest by collecting a large heap of decaying
         vegetable matter, which generates heat sufficient to
         hatch the numerous eggs (sometimes half a bushel)
         deposited in it by the females of the flock.
