Chimpanzees use a variety of vocalizations, gestures, and facial expressions to communicate with each other. Their calls can convey different messages, such as alerting others to danger or signaling the presence of food. These vocalizations are often context-specific, meaning the same sound can have different meanings depending on the situation. In addition to vocal sounds, chimpanzees also rely on body language and physical gestures. For example, they may use hand signals or touch to express affection or establish social bonds. This complex communication system helps maintain social structures and relationships within their groups.
