White-Handed Gibbon, Kaeng Krachan National Park, Thailand

One of the handful of white-handed gibbons that I saw while in Thailand. These guys come in two colors — darker, almost black fur like this one, and also a much lighter, beige color. This gibbon had been quickly moving through the canopy, calling his mate for quite a while as I was scurrying below trying to find an opening in the foliage to grab a shot or two. Nikon D500 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/160th of a second.
