A silverback mountain gorilla cradles his head jungle of Rwanda's Virunga Mountains. This was the second-ranked silverback in the family. Nearby, a smaller female sat in a clump of grass. Apparently, while the lower-ranked silverbacks are not supposed to mate with the females, they will sometimes sneak away from the family group and secretly do so. If the top silverback catches them, he will punish them.
