This dusky langur caught me off guard. I was walking around the campground that I was staying at in Kaeng Krachan National Park in Thailand when he/she suddenly appeared on a branch just above me. I had to quickly zoom all the way to the short end of my 200-400mm lens but was able to get off a few shots just as the sun hit the langur’s face.
