Gorillas - Rank Order

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.
