Silverback Mountain Gorilla, Mgahinga, UgandaSilverback mountain gorillas weigh in excess of 400 pounds. They eat about forty pounds of leaves, stems, shoots and fruits a day. This silverback was taking a break from all that eating and just hanging back, relaxing, and watching the rest of the family go about their business. He is one of three silverbacks in a family of ten that roam the base of Gahinga Volcano in the southwestern corner of Uganda. Nikon Z8 with Nikkor 70-200mm lens (at 150mm) ISO 3600, f/2.8 at 1/640th of a second.
