How do chimpanzees communicate?
Since they do not have the ability to use language the way we do, they communicate with each other actively using vocalizations, body language as well as facial expressions. Chimps have a wide range of call for different purpose : anger, grieve, anxiety, fear etc. The acknowledge each other by either calling out loud, making specialized sounds among the same group, and they alert each other that danger is approaching by screaming, jumping up and down a tree branch, shaking the leaves, etc. The way they sit (posture) also tells a lot about how a chimp is feeling. Each posture describes a different set of feelings and whether the chimp is open to socialize or putting up a Do Not Disturb sign.
