Habitat
Francois' langurs primarily inhabit subtropical and tropical forests in southern China and northern Vietnam. They prefer limestone karsts, hilly terrains, and areas with dense canopy cover for protection and foraging. These environments provide the foliage and shelter essential for their survival.
Diet
Their diet mainly consists of leaves, fruits, and flowers, with a strong preference for young, nutrient-rich leaves. They engage in selective feeding during the day, often spending hours in the treetops to browse. Feeding behavior includes occasional supplementation with buds and seeds to meet nutritional needs.
Behavior
Francois' langurs live in social groups typically led by a single adult male with several females and their young, exhibiting territorial behaviors through vocalizations and displays. They are diurnal and arboreal, spending most of their time in trees to forage and rest. These groups communicate with a variety of calls and are known for their agile movements to evade threats.
Conservation Status
The IUCN classifies Francois' langur as Endangered, with populations declining due to habitat loss from deforestation and hunting for the pet trade. Major threats include fragmentation of forest habitats and human encroachment.
