Hairy Saki Distribution

Hairy Saki Characteristics

The hairy saki[1] (Pithecia hirsuta) is a species of saki monkey, a New World primate species.

  • These Sakis are distinguished by their small size of 30 to 50 cm and a very heavy, dense, non-prehensile tail, adding 25 to 55 cm to their body length.
  • The hairy saki’s face is partially bald but has a beard and a hood of curly black hair covering its forehead.
  • The nostrils are positioned laterally on the face. These sakis are generally black, but their feet and hands are light in color.
  • These coloring patterns can be considered the most uniform and simplest of the sakis, with very little difference in coloration between males and females. Both are primarily blackish agoutis.

Hairy Saki Facts

  • The species was identified by Johann Baptist von Spix in 1823 but later merged with the Mönk saki (P. monachus). Then, a 2014 study revived it as a separate species due to differences in fur coloration.
  • Hairy sakis are believed to be threatened by deforestation and poaching; therefore, their population is in decline.
  • Adults recognize their mates by highly specialized vocalizations; acoustic cues such as trills, whistles, and screeches are used for low-intensity aggression.
  • Family groups are nuclear families formed by a monogamous couple and their young.
  • Hairy sakis practice extensive allogrooming as a general social behavior that is not sexually oriented or motivated.
