Gorontalo Macaque Characteristics

Gorontalo Macaque

The Gorontalo macaque[1] (Macaca nigrescens), also called the Dumoga-bone macaque, is a species of the primate of the Cercopithecidae family.

  • Dumoga-bone Macaques are native to the Northern Sulawesi Island of Indonesia. Gorontalo macaques are large diurnal primates with black bodies and faces.
  • Their faces are black and sparsely covered with fur, and their fur is coarse, dense, and shaggy.
  • Juvenile Gorontalo macaques are paler than adults and appear brown instead of black. In addition, juveniles have black fur where the crest develops.
  • As adult male species age, their hair turns grizzled and gray, most noticeable on the upper body; it also sometimes occurs in the arms of younger men.

Gorontalo Macaque Facts

  • Gorontalo macaques are diurnal, spending 59 percent[2] of their waking time moving, feeding, and foraging.
  • Female species have an egalitarian social structure, while men form a linear and transitive domination hierarchy.
  • Groups are typically tolerant, characterized by displays of appeasement, minimal aggression (biting), and “symmetry in conflict“.
  • Male Gorontalo macaques exhibit a wide range of signals to indicate aggression: open-mouth stares, closed-mouth grins, yawning, swinging, and chasing.
  • They usually gather in the morning, rest in the afternoon, and roost in trees.

  1. Hello,
    I just found the page on the Gorontalo macaque.
    First, I think the picture is one of a Macaca nigra (black-crested) and not a Macaca nigrescens (Gorontalo, without crest)
    And for the distribution, it can only be found in a small part in North Sulawesi, not in all Indonesia.
    Thanks !
