Pagai Island Macaque Characteristics

Pagai Island Macaque

The Pagai island macaque[1] (Macaca pagensis), also called the Pagai or Bokkoi macaque is an Old-World monkey native to the Mentawai Islands on the west coast of Sumatra.

  • Male Pagai Island macaques are generally larger than females. The body length of males is 45 to 55 cm, and females are about 40 to 45 cm.
  • Tail length is 13 to 16 cm in males and 10 to 13 cm in females. Males are also heavier, weighing between 6 and 9 kg, while females weigh between 4.5 and 6 kg.
  • Their back is dark brown and chestnut to light brown on the sides of the neck, front of the shoulders, and underside of this species.
  • The legs are brown, and the arms are reddish brown. Mentawai macaques’ faces are hairless, and they have black skin and brown eyes.

Pagai Island Macaque Facts

  • They live above the forest floor in the canopy, forage between 24 and 36 meters, and can perch up to 45 meters high.
  • Groups of Pagai Island macaques consist of approximately 5 to 25 individuals. A troop generally contains 1 alpha adult male and several females and their young.
  • The male is the ultimate authority on where the troop forages and communicates it to the rest of the group with high-pitched calls.
  • Solitary, roaming Pagai Island macaques challenge the dominant male for his position, resulting in aggressive fights.
  • If they detect predators, these macaques will notify the rest of the group with a short, harsh bark.
