Habitat
Pig-tailed langurs primarily inhabit lowland and hill rainforests in Sumatra, Indonesia, preferring dense vegetation in areas up to 1,500 meters elevation. They thrive in primary and secondary forests with abundant canopy cover for foraging and shelter. Geographic preferences are limited to this island region due to their specialized needs.
Diet
They mainly consume leaves, fruits, and flowers, with a strong preference for young leaves and seasonal fruits. Feeding behavior is diurnal and arboreal, occurring mostly in the treetops to avoid ground predators. They occasionally eat bark or insects when other food is scarce.
Behavior
Pig-tailed langurs live in small family groups of 2-10 individuals, typically led by a dominant male. They are diurnal and arboreal, spending most of their time foraging in trees and exhibiting territorial vocalizations to defend their range. Notable behaviors include grooming to strengthen social bonds and remaining quiet to avoid detection by predators.
Conservation Status
The IUCN status is Endangered, with population trends showing a rapid decline due to habitat loss from logging and agriculture. Major threats include hunting for the pet trade and forest fragmentation.
