Habitat
Gray-shanked doucs inhabit primary and secondary rainforests in central Vietnam and possibly Laos, preferring mountainous regions with dense canopy cover. They are arboreal, spending most of their time in the upper levels of the forest, and avoid open areas due to vulnerability to predators.
Diet
Gray-shanked doucs primarily eat young leaves, fruits, and flowers, with a preference for nutrient-rich foliage. They forage during the day in the treetops, spending several hours feeding to meet their high-fiber dietary needs. Feeding behavior includes selective browsing to avoid toxic plants.
Behavior
Gray-shanked doucs live in social groups of 4-15 individuals, typically led by a dominant male, and communicate through vocalizations and body language. They are diurnal and highly arboreal, spending their time leaping between trees and resting in the canopy, while being territorial and defending their home ranges from other groups. Males may engage in displays to ward off rivals, and the species is known for its cautious and alert nature in the wild.
Conservation Status
The IUCN status of the gray-shanked douc is Endangered, with populations declining due to habitat loss from deforestation and hunting for the pet trade. Major threats include fragmentation of rainforest habitats and human encroachment.
