“This, coupled with his inability to successfully service his females, led to a gradual reduction of the family size,” the authority said. After a series of debilitating raids from wild gorilla groups, Ruhondeza’s reign eventually collapsed in March. “He was seriously beaten,” rangers said. He was forced to live alone, on private land adjacent to the park, and although efforts were made to reintroduce him to the area, which is home to about 320 mountain gorillas — half the world’s population — all were unsuccessful. “By the time of his banishment to solitary life, the family had reduced to six,” the wildlife authority added.
