Black Uakari Characteristics

Also called the golden-backed black uakari, golden-backed uakari, and Homboldt’s black-headed uakari, the black uakari[1], is a species native to southwestern Venezuela, southeastern Colombia, and northwestern Brazil.

  • The black uakari has a short tail relative to its body size, with a tail length of less than 50 percent of the combined body and head length. In addition, its tail is not prehensile.
  • The species is further divided into 2 subspecies: C. m. ouakary is distinguished by a yellowish or golden nape and mid-dorsum from C. m. melanocephalus, in which these body regions are black to reddish-brown.
  • The rest of the body is dark brown, except for the abovementioned areas that distinguish the subspecies.
  • The lower jaw is deep in the region of the symphysis and exceptionally robust.

Black Uakari Facts

  • The face of Cacajao melanocephalus is black and bare, hence the common name “black uakari” or “black-faced uakari“. The hands and lower limbs are black too.
  • Although their canines are known to be up to 14 mm long, like their incisors, they are a critical food specialization, allowing them to consume hard fruits and thick-shelled seeds.
  • Social grooming is this primate’s most common tactile behavior. In addition to strengthening social bonds, social grooming helps remove parasites and dead skin cells.
  • The females issue a scent to attract a male suitor to reproduce.
  • Because they often eat ripe fruit and fruit seeds, the black uakari, like most frugivores, plays a vital role in seed dispersal.
