Definitely my favorite Zoo couple!! These White Faced Gibbons are always fun to watch and photograph at Denver Zoo. Their habitat is mostly outdoors with ropes hanging high over the walking path. Here they're sitting on their island, just grooming each other. This behavior continued for over an hour, so many great photos and moments. Used Sony Alpha A77II Camera, Sony 70-300mm G lens. ISO 200- f/10 at 1/125 sec. December 2017.
