Capuchinbird Perissocephalus tricolor

  • Order: Passeriformes
  • Family: Cotingidae
  • Monotypic
  • Authors: Jack Hruska and Guy M. Kirwan


Distinguishing Characteristics

Capuchinbird is a large, odd looking bird with a short tail, bald blue gray head and a heavy bill. The plumage is mostly ochre brown, darker on the rump, and is reddish chestnut on the belly. The undertail coverts, which are orange rufous, are long and curled in the male, and are capable of being raised out like globular orangish "tail lights" during lekking displays. The undertail coverts of females, however, are not lengthened. The wings and tail are blackish, with white underwing coverts.

Restall (2006) et al. suggested that Capuchinbird may "recall a small Black Vulture [Coragyps atratus] with its bare head and uniform mantle".

Similar Species

Wthin its range Capuchinbird is essentially unmistakable. The combination of its "cowled" head, large size, and ochraceous brown coloration contribute to a strange but unique appearance.

Detailed Description

The following detailed description is based on Kirwan and Green (2011):

Adult: Sexes similar, although the male is larger (see Measurements) and has longer undertail coverts. Large, bulky, with short tail, heavy bill, and bare crown. Upperparts generally dill cinnamon. Feathers on the back of the head dense and upright standing, forming a prominent cowl, and imparting a "hunchbacked" appearance. Uppertail coverts blackish with dull cinnamon tips. Remiges blackish, outer webs of the tertials with brownish fringes. Rectrices black. Underparts deeper cinnamon, especially from the breast to the vent. Undertail coverts of male long and orange rufous; undertail coverts short in female. Underwing coverts creamy white.

Juvenile: Similar to adult, but has sparse down on the bare areas of the head.

Nestling: Covered in orange down.


Little information. Molt apparently is very protracted, and may extend over as many as 220 days (Snow 1976). In Guyana molt is initiated in March-July, but in other regions the timing of molt is less well defined (Kirwan and Green 2011).
