This striking Celeus is widespread across the Amazonian lowlands of northern South America, with a disjunct population in southeast Brazil. Overall rufous with a shaggy crest like most other members of the genus. Distinctive and unlikely to be confused. Some variation across the range: most have extensive black markings on upperparts and belly, but largely unmarked in the northeastern part of range. All birds have solid black breast. Sexes are similar, but males have a red mustache. Occurs in mature forest and edges, often detected by its series of loud, strident whistles.
