The Umubano Gorilla Family consists of 11 individual mountain gorillas. The group is lead by a dominant silverback and it has 1 black back, 3 females and 6 young mountain gorillas.
This group was once part of the Amahoro Group. It separated from the Amahoro group after a fight that saw Charles the dominant silverback of Umubano winning Ubumwe (the dominant silverback of the Amahoro group).
Charles left Amahoro with a number of females and from then, Charles has been controlling the family. However, there have been normal interactions between him and Ubumwe and no fights have been reported.
