The Nilgiri Langur is one of the mammals assessed by the IUCN Red List, so it has a page here — with its scientific name, Semnopithecus johnii, its conservation category and, where one is known, a recorded observation on the map. What is missing is the rest: habitat, distribution, diet, behaviour, threats and the conservation work under way.
Each profile is researched and checked one species at a time, and there are thousands to go. You can put this one at the front of the queue.
In the meantime, the full assessment is on the IUCN Red List.
