Female Proboscis Monkey, Tanjung Puting National Park, Borneo, Indonesia

I think this female proboscis monkey just realized what her male counterparts looked like (see this previous post for the male). It was fun to photograph these iconic monkeys from the platform of a small boat while I was floating down a river through Tanjung Puting National Park in Indonesian Borneo. Nikon D300 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/5.6 at 1/200th of a second.
