Gorilla Groups

More than half of all mountain gorillas are habituated, meaning they are used to the presence of humans. While some groups are only observed by researchers, most are however visited by tourists. Thanks to the daily recordings made by the rangers we are able to closely track the comings and goings in these groups. Their sizes are constantly changing; it is not uncommon for whole families to dissolve, for groups to split, or for silverbacks to form new groups of their own.
