Secretary \Sec"re*ta*ry\, n.; pl. {Secretaries}. [F.
   secr['e]taire (cf. Pr. secretari, Sp. & Pg. secretario, It.

   {Secretary Bird}. [So called in allusion to the tufts of
      feathers at the back of its head, which were fancifully
      thought to resemble pens stuck behind the ear.] (Zo["o]l.)
      A large long-legged raptorial bird ({Gypogeranus
      serpentarius}), native of South Africa, but now
      naturalized in the West Indies and some other tropical
      countries. It has a powerful hooked beak, a crest of long
      feathers, and a long tail. It feeds upon reptiles of
      various kinds, and is much prized on account of its habit
      of killing and devouring snakes of all kinds. Called also
      {serpent eater}.
