Chimpanzees live in communities of up to 150 individuals, but they spend most of their time in smaller groups of friends and family. They groom each other — carefully picking through each other's fur — to show friendship and to keep clean. They hug, hold hands, and even kiss when they greet each other, which can look very familiar to us.
Chimps are remarkable tool users. They strip the leaves from twigs to make a stick, then poke it into a termite mound and pull it out covered in termites to eat. They crack open hard nuts by using a flat stone as an anvil and another stone as a hammer. These skills are passed down from mothers to children, just like a human tradition.
In the forest, chimpanzees build a fresh sleeping nest every single night — bending and weaving branches together high up in a tree, away from most predators. At dawn they greet the morning with a burst of loud calling called a 'pant-hoot'. When one chimp starts, others join in, and the sound echoes across the whole forest.
