Banded Langur, ThailandI photographed two species of langur on my short trip to Thailand back in 2016. This is the Robinson’s banded langur, otherwise known as the Robinson’s banded surili. At the time I took this photograph, it was still considered a sub-species of another type of langur but in 2019 genetic analysis determined it to be its own species. Always interesting to find out that what scientists thought was true of an animal when I took a photograph is no longer the case. Nikon D500 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/125th of a second.
