Kamichi \Ka"mi*chi\, n. (Zool.)
   A curious South American bird (Anhima  or {Palamedea
   cornuta), often domesticated by the natives and kept with
   poultry, which it defends against birds of prey. It has a
   long, slender, hornlike ornament on its head, and two sharp
   spurs on each wing. Although its beak, feet, and legs
   resemble those of gallinaceous birds, it is related in
   anatomical characters to the ducks and geese (Anseres).
   Called also horned screamer. The name is sometimes applied
   also to the chaja. See Chaja, and Screamer.
