Most mountain gorillas live in stable family groups of around 10 individuals, with one dominant male and several females. Both males and females in the group care for their infants; hugging, carrying and playing with them.
When they get older, most males and around 60% of females then leave their birth group to join another troop. This helps prevent inbreeding.
What is this Silverback doing – protecting his family, looking for food or looking to join another group?
