Chimpanzee, Kibale National Park, Uganda
Chimpanzees can be difficult to photograph in the wild. They spend most of their time high in the canopy set against the bright white backdrop of the sky. After several days trying to get decent shots, I finally came upon a troop closer to the ground. This female saw me through the opening in the tree before scampering off to higher ground.
