Long-Tailed Macaque, Malay Peninsula, Thailand

Long-tailed macaques, also known as crab eating macaques, are fairly common monkeys in southeast Asia and they can often be spotted living amongst human populations. This guy looks to be out on some wild mountainside, but he was actually above a temple that sees quite a bit of daily foot traffic. He was calling across an open area to the macaques on the other side. Nikon D500 with Nikkor 200-400mm lens (at 200mm) ISO 800, f/4 at 1/640th of a second.
