Last year , a silverback alpha male gorilla , the leader of his group , and three females were shot and killed in virunga national park , in the democratic republic of congo .
As the leader of a family group that can be as large as 30 individuals , they will lead their underlings to food , settle disputes within the clan , and fight to repel outside threats , particularly from other male gorillas , who will kill babies when seeking to usurp a silverback 's group .
Kabatwa , a silverback mountain gorilla , carries her twins in the virunga mountains , just outside north-western rwanda 's volcanoes national park in kinigi .
But that pattern differs from the one observed in gorillas , where a dominant " silverback " male usually mates with multiple females , and other males are forced to leave the group .
