Mgahinga is home to the habituated Nyakagezi gorilla group - a fairly nomadic bunch that have been known to cross the border into Rwanda and the Congo. The family includes the lead silverback Bugingo who is around 50 years old and father to most of the group; his silverback sons, Mark and Marfia; and two blackbacks, Rukundo and Ndungutse, who love to pose and play in the trees. The two females, Nshuti and Nyiramwiza, both have babies Furraha and Nkanda respectively.
