Identification and description:
The François' Langur, or Trachypithecus francoisi, is an arboreal primate native to the subtropical forests of Southeast Asia, particularly in Vietnam, China, and Laos. This monkey is easily recognizable by its shiny black fur contrasted by a distinctive white band extending from each side of its face. François' langurs live in social groups led by a dominant male and several females. They primarily feed on leaves, fruits, and flowers, making them dependent on dense forests for their diet. Unfortunately, this species is threatened by deforestation and hunting, leading to a significant decline in its population.

Recommended lens:
400 mm – adjust based on distance, desired framing (portrait or habitat), and approach conditions.

Photography tips:
To photograph the François' Langur, it is advisable to use a telephoto lens of at least 400mm to capture detailed images without disturbing the animal. The subtropical forests where they live often provide changing light conditions, so adjusting ISO and aperture may be necessary to achieve good exposure. Be patient and discreet, as these monkeys can be shy. Observing their social behavior can offer unique photo opportunities.
