Siberut Langur Distribution

Siberut Langur Characteristics

Siberut Langur

The Siberut Langur[1] (Presbytis siberu) is a monkey species in the Cercopithecidae family.

  • It was previously thought to be a subspecies of the Mentawai langur, Presbytis potenziani (like Presbytis potenziani siberu). Still, genetic analysis has shown them to be separate species.
  • Siberut langur infants are born with white coats. After 2 to 3 weeks, the coat begins darkening, and the face takes on a dark pigmentation.
  • This color change begins at the dorsal midline and head and ends laterally.
  • After 3 months, the belly and chest are dark reddish brown, the cheeks, throat, forehead, and tip of the tail are white, and the rest of the body is jet black. Males are distinguished from females by a patch of white fur around the genital area.
  • Sibirut langurs have slender bodies with hind legs that are longer than their forelegs.

Siberut Langur Facts

  • Siberut langurs are native to the islands of North Pagai, South Pagai, and Sipora.
  • These Old-World primates roost in the upper middle tiers of trees above 20 meters (66 ft), where canopy density is the thickest. The most common locations are coconut palms.
  • They move by walking and climbing on all fours. They also jump into the middle and upper canopy and fall when approaching the ground.
  • Siberut langurs spend over 80 percent of their time resting and foraging and only a tiny portion traveling and socializing.
  • Adult males usually separate from the group early in the morning and emit long calls.
