The Dusky Leaf Monkey (Trachypithecus obscurus) also known as a Spectacled Langur or Spectacled Leaf Monkey.
The dusky leaf-monkey is a folivorous species (eats leaves) but it will also consume fruit and flowers.
They prefer to forage high up in the main canopy of the forest.
When feeding this species will sit on large branches and boughs.
They will spread foraging activity throughout the day so they do not overload their digestive processes that remove plant toxins and process leaf matter efficiently
