Gray-shanked Douc Distribution

Gray-shanked Douc Langur Characteristics

The gray-shanked douc langur[1] (Pygathrix cinerea) is a species of douc endemic to the Vietnamese provinces of Gia Lai, Quảng Ngãi, Kon Tum, Bình Định, and Quảng Nam.

  • Gray-shanked Douc langur’s body, crown, and arms are mottled light gray with a lighter underside.
  • The shoulders, thighs, and part of the rump are marked with white spots. In addition, the feet and hands are black, while the lower legs are mottled dark grey.
  • The bare skin of the face is yellowish brown, except for the areas around the chin and mouth, which are white.
  • Long white fur covers the sides of the face. This colorful monkey has a white throat with a band of orange collar outlined by a black line connecting the black spots on their shoulders.
  • Gray-shanked douc langur tails are almost the same length as the total length of the head and body.
  • Genetically, Gray-shanked douc langurs are similar to Red-shanked douc langurs (Pygathrix nemaeus); however, they are considered separate species based on morphological differences.

Gray-Shanked Douc Langur Facts

  • Male species are the dominant sex, and dominance hierarchies have been observed in captivity.
  • In the past, they have been found in groups of up to 50 individuals. Still, this number has been significantly reduced to between 4 and 15 individuals.
  • Gray-shanked douc langurs are also dedicated to grooming to remove parasites and create and strengthen bonds between group members. This typically happens before bedtime.
  • Group members will usually spar with one another. Sparring is aggressive behavior in which participants grab, pull, and slap each other.
  • Facial expressions include grimaces used to show submission, a playful face used to play with another group member, and stares that suggest aggression or curiosity.
