A large black-and-white carrion-eating stork of the genus Leptoptilos (formerly Ciconia), esp. the African species (Leptoptilus crumeniferus syn. Leptoptilos crumenifer), whose downy under-wing feathers are used to trim garments; called also marabout. The Asiatic species (Leptoptilos dubius, or Leptoptilos argala) is the adjutant. See Adjutant.
A kind of thrown raw silk, nearly white naturally, but capable of being dyed without scouring; also, a thin fabric made from it, as for scarfs, which resembles the feathers of the marabou in delicacy, -- whence the name.
Turkey feather fibers used extensively as wings and tails of lures/streamers
