Red-shanked Doucs

“Queen Of Primates”

Known as the “Queen of primates,” these langurs boast a vivid, multi-coloured appearance, making them among the most striking primates. Primarily arboreal, they spend most of their time high in the forest canopy, even sleeping there.

Generous Nature

Red-shanked doucs mainly eat leaves, relying on a four-chambered stomach that ferments fibrous plant material.

With that said, they are still rather flexible eaters, consuming a wide range of foods throughout the seasons.

Remarkably, these langurs share meals, peacefully breaking foliage and passing it to one another, showing a communal and generous nature when foraging.

Distinct Communicators

Red-shanked doucs also use a variety of facial expressions for communication, including a “play face” - a partially bared mouth and chin thrust forward.

They also have distinct signals, like a fixed stare for threats and a grimace for submission. During play, they sometimes blink to display their light blue eyelids.

Agile Aerialists

Living in groups averaging 18 members, red-shanked doucs are agile aerialists, leaping up to six metres in the forest canopy.

Adult males lead the group during movement, with juveniles in the rear and females and infants safely in the middle.

Although their tails aren’t prehensile, they use them for balance while navigating the treetops.

Critically Endangered

In 2020, the IUCN classified red-shanked doucs as critically endangered due to their continuous declining population.

Hunting poses a severe threat, driven by demand for meat, traditional medicine, and the pet trade.

Habitat fragmentation and agricultural land conversion further endanger the species, making conservation efforts crucial for their survival.

Together, We Protect Wildlife

Breeding success

Breeding success

We are proud to have successfully bred critically endangered species like the red-shanked doucs in our parks.

Their birth aligns to our long-term managed plan to sustain the population of this critically endangered leaf monkey under our care.

Association Anoulak is committed to conserving threatened wildlife in Laos PDR, including the critically endangered red-shanked douc, white-cheeked gibbon, and saola.

Since 2015, we have supported large-scale monitoring efforts in the Annamite Mountains to guide effective conservation strategies.

By removing snares and reporting illegal activities, they help enforce laws and protect forest wildlife in Nakai-Nam Theun National Park.
