Northern Buffed-cheeked Gibbon Characteristics

Northern Buffed Cheeked Gibbon

The northern buffed-cheeked gibbon[1] (Nomascus annamensis) is a species of crested gibbon recently discovered in Vietnam, Laos, and Cambodia.

  • The northern buffed-cheeked gibbon resembles Nomascus gabriellae in appearance.
  • Males and females of Nomascus annamensis differ in color and morphology.
  • The male primarily has black fur that shimmers silver in the sun and a light brown chest.
  • The cheeks are dark orange, and the crest is very prominent. However, the female lacks the distinctive crest and is tan-orange.

Northern Buffed-Cheeked Gibbon Facts

Nomascus Annamensis

  • Northern buffed-cheeked gibbons live almost exclusively in trees and rarely leave the canopy’s comfort and safety.
  • This gibbon can project up to 10 m (33 feet) between branches at peak speed! However, he manages to do so with the greatest elegance and grace, his movements flowing harmoniously into the next and coming to perch on a branch in a calm and controlled way: perfectly composed.
  • High in the canopy where predators can’t reach them, Northern buffed-cheeked gibbons spend the day foraging and feeding, the young find time to play, and the parents relax or care for each other or their young.
  • When they are not trying to find a mate, gibbons tend to socialize only with their immediate family members.
  • Family members spend their mornings reconnecting, eating, or traveling for food.
