The Collaborative International Dictionary of English v.0.48:

Motmot \Mot"mot\, n. [Cf. Momot.] (Zool.)
   Any one of several species of long-tailed, passerine birds of
   the genus Momotus, having a strong serrated beak. In most
   of the species the two long middle tail feathers are
   racket-shaped at the tip, when mature. The bird itself is
   said by some writers to trim them into this shape. They feed
   on insects, reptiles, and fruit, and are found from Mexico to
   Brazil. The name is derived from its note. [Written also
   momot.]
   [1913 Webster]
