My first encounter with this Macaque was in the village of Parambikulam on which name Parambikulam Tiger Reserve exists in the State of Kerala just adjacent to Top Slip area of the Anamalai Wildlife Sanctuary also known as Indira Gandhi Tiger Reserve in Tamil Nadu.
It is also known as Zati and is very sociable. They co-exist with the grey langurs without any competition. They feed on fruits, nuts, flowers and invertebrates. They also on the look out for the food from human beings. Hence they are found sitting on the roadside and waiting for the vehicle to slow down and offer them food.
They are comfortable on trees as well as on the ground. As we humans have encroached into their area they have started living near the human settlements for their basic necessities. During my journey in Tamil Nadu and Kerala, I happen to see them at a number of places.
