The Capuchinbird or Calfbird (Perissocephalus tricolor) is a species of bird in the Cotingidae family. It is monotypic within the genus Perissocephalus. It is found in humid forests in north-eastern South America, almost entirely north of the Amazon River and east of Rio Negro. A thickset bird with a relatively heavy bill, its plumage is overall rich brown approaching orange on the belly and undertail coverts and the remiges and short tail are black. The most distinctive feature is its bare, almost vulture-like head covered in dull blue skin. They gather in leks where they "sing". The "song" is very odd and difficult to describe accurately, although some have compared it to the distant sound of a chainsaw or (as indicated by its alternative name Calfbird) a cow mooing.
