Social grooming is a behavior observed in many animal species, including primates and some birds, where individuals engage in activities like cleaning each other's fur or feathers. This practice helps maintain hygiene and strengthens social bonds within a group. By grooming one another, animals can reduce stress and promote cooperation, which is essential for group living. In addition to its physical benefits, social grooming serves as a form of communication. It allows animals to establish and reinforce social hierarchies and alliances. For example, in groups of chimpanzees, grooming can indicate friendship and support, enhancing the overall cohesion of the community.
