Chimpanzee trekking is often imagined as a peaceful walk through the forest.
You hear birds.
Leaves move above you.
Then you find a chimpanzee feeding quietly in a tree.
But chimpanzee society has another side.
Chimpanzees can become aggressive when social relationships become tense, when individuals compete for rank or mates, and when neighbouring communities meet around territorial boundaries. Researchers have documented males forming patrols and responding aggressively to members of other communities.
Kibale National Park has become an important place for understanding this behaviour because scientists have studied its chimpanzee communities for decades.
At Ngogo, researchers documented the permanent separation of a large chimpanzee community into different groups, followed by hostile interactions between the newly separated communities. Some encounters involved charging and chasing, while some attacks were fatal.
It sounds dramatic, but there is an important lesson here.
Wild animals donāt behave for our entertainment.
Their actions are connected to survival, territory, food, social relationships and reproduction.
And chimpanzees are not aggressive all the time.
They also groom one another, cooperate, communicate, play and maintain strong social bonds.
That is what makes Kibale so fascinating.
A chimpanzee trek isnāt simply about taking a photograph of a primate.
It can become a lesson in animal behaviour, social relationships and conservation.
Next time you watch chimpanzees, look beyond the face.
What are they communicating to each other?
Would you know an aggressive display if you saw one?
