Brown Capuchin, Madidi National Park, BoliviaThis is the brown capuchin monkey, also commonly known as the tufted capuchin. It used to be believed to be one of the most widespread monkeys in the Neotropics but has since been divided into several different species, including the black-striped, black and golden-bellied capuchins. The brown/tufted lives only in the Amazon basin and surrounding areas. I photographed this one in the Bolivian Amazon at a great national park called Madidi. I was in a canoe on one of the park’s lakes when a few of these guys appeared above the shoreline. Nikon D700 with Nikkor 200-400mm lens (at 380mm) ISO 1600, f/4 at 1/100th of a second.
