Habitat
Hatin langurs primarily inhabit tropical and subtropical moist broadleaf forests, especially limestone karst formations in central Vietnam and Laos. They prefer dense canopies and hilly terrain for protection and movement, avoiding open areas and human settlements.
Diet
Hatin langurs mainly consume leaves, buds, and fruits from a variety of trees, with a preference for young, nutrient-rich foliage. They are folivorous and spend much of their day foraging in the canopy, typically feeding more actively in the early morning and late afternoon to avoid midday heat.
Behavior
Hatin langurs live in social groups of 5-20 individuals, usually led by a dominant male, and they communicate through vocalizations, facial expressions, and body postures. They are diurnal and arboreal, spending most of their time in trees to forage and rest, while exhibiting territorial behaviors like branch-shaking to defend their range.
Conservation Status
The IUCN classifies the Hatin langur as Endangered, with populations declining due to habitat loss from deforestation and hunting for the wildlife trade.
