Description:
The Trachypithecus vetulus, commonly known as the Purple-faced Langur, is a primate endemic to Sri Lanka. This monkey features dense fur ranging from dark brown to black, with a distinctive purple-tinged face. It primarily inhabits tropical rainforests, lowland forests, and mountainous areas. Being diurnal, it spends most of the day foraging for leaves, fruits, and flowers. Purple-faced langurs are social animals living in family groups led by a dominant male. Unfortunately, their habitat is threatened by deforestation, leading to a decline in their population. They are currently classified as vulnerable by the IUCN.

Recommended lens:
>=400mm

Photography tips:
To photograph the purple-faced langur, it is advisable to use a telephoto lens of at least 400mm to capture detailed images from a distance without disturbing the animal. The tropical forests they inhabit often provide dim lighting, so adjusting the aperture and ISO sensitivity may be necessary to achieve proper exposure. Be patient and discreet, as these primates can be suspicious. Observing their social behavior can offer unique photo opportunities.
