Habitat
This species primarily inhabits dense evergreen and semi-evergreen forests in Southeast Asia, including limestone karsts and hilly regions. They prefer areas with tall trees for foraging and shelter, mainly in Vietnam, Laos, and Cambodia. These habitats provide ample foliage and proximity to water sources.
Diet
Indochinese black langurs mainly eat leaves, young shoots, fruits, and flowers, with a preference for nutrient-rich foliage from various tree species. They forage during the day in groups, spending significant time in the canopy to access food, and occasionally supplement their diet with insects or buds.
Behavior
These langurs are highly arboreal and diurnal, spending most of their time in trees where they move in agile leaps. They live in multi-male, multi-female groups of 10-50 individuals, exhibiting strong social bonds through grooming and vocalizations, and they defend territories using alarm calls. Males may display aggression to protect the group, while females play a key role in infant care.
Conservation Status
The IUCN status of the Indochinese black langur is Endangered, with populations declining due to habitat loss and hunting. Major threats include deforestation for agriculture and illegal wildlife trade.
