My favorite monkeys are the White Faced Gibbons. Always stop by to see what shenanigans they're up to at Denver Zoo. The pair is always out, playful and very photographic!! I love spending time with them. This female spent some time just staring at me, not many other folks around. I just love when the sunlight hits just right!! Used Sony Alpha A77II camera, Sony 70-300mm G lens. ISO 400 - f/7.1 at 1/320 sec. September 2017.
