\Tro"gon\, n. [NL.] (Zo["o]l.)
Any one of numerous species of beautiful tropical birds
belonging to the family {Trogonid[ae]}. They are noted for
the brilliant colors and the resplendent luster of their
plumage.
Note: Some of the species have a train of long brilliant
      feathers lying over the tail and consisting of the
      upper tail coverts. Unlike other birds having two toes
      directed forward and two backward, they have the inner
      toe turned backward. A few species are found in Africa
      and India, but the greater number, including the most
      brilliant species, are found in tropical America. See
      Illust. of {Quesal}.
