Nilgiri Langurs, or Nilgiri Leaf Monkeys are an endangered species of old world monkeys found mainly in South India. As I was driving along one of the roads in the reserve, I spotted a group of these Langurs hanging around on the trees overhead, watching the cars and people pass by.
These monkeys used to be a common species in India, but are now considered endangered due to excessive poaching and habitat loss which has resulted in a drastic decrease in their population. I spotted one individual during the boat ride too, but only for a few seconds short of grabbing a shot. The ones here were difficult to photograph as well as the back-light made their bodies dark and unrecognizable.
Anyway, the extremely common Lion-Tailed Macaques were abundant in the reserve.
