In a group of gorillas there is a clear hierarchy. The leading silverback
has the highest rank, and adult females are dominant over young animals.
Among the females, rank depends on factors such as how long they have
been in the group, for example. Among the young animals, rank usually
depends on age.
A gorilla male achieves his high-ranking position not only because of
his strength, which he proves when fighting against competitors, but also
because of his experience and abilities. For instance, he has to know
the area very well in order to lead his group to the right feeding sites
at the right time of the year. These days, it is also very important that
he knows how to deal with humans. Experienced gorilla males can, for example,
remove poachers' snares from the hands or feet of their group members.
As young males lack the necessary experience, they will find it difficult
to lead a group: If the females notice that their silverback male is too
inexperienced, they will transfer to another one.
