Germain's Langur

Trachypithecus germaini

Also known as Indochinese Lutung, Germain's Silvered Langur, Indochinese Silvered Langur

Germain's langurs are elegant, dark grey arboreal primates distinguished by long crests of hair atop their heads and prominent white-to-grey whiskers framing dark faces. Infants are born bright orange, turning dark grey as they mature over several months. These canopy-dwelling leaf eaters move in small family groups through dry evergreen, riverine, and mangrove forests across Mainland Southeast Asia.

What to notice
Distinctive dark grey langur with an erect hair crest, pale whiskers, and long tail, seen in upper canopy layers.
Support conservation
Keep noise to a minimum, refrain from disclosing precise GPS coordinates of wild groups, and never purchase wild-caught pets.
Responsible observation
  • Keep Your Distance: Use binoculars or a telephoto lens to view these shy canopy dwellers without causing distress.
  • Avoid Direct Eye Contact: Staring directly at primates can be interpreted as a threat or aggressive challenge.
  • Do Not Feed: Feeding wild monkeys disrupts natural foraging habits and increases human conflict.
