Although not known for their generosity, chimpanzees do regularly share food. Most chimpanzee food sharing does not involve actively handing food to someone else, but rather passively allowing another individual to take it. Aware of this possibility, chimpanzees often beg for food from those who have it – holding out a hand or even reaching toward another’s mouth as he chews. Foods that are shared are those that are high-value, monopolizable, and rare, such as meat, honey, or large fruits. Food sharing appears to strengthen social bonds in chimpanzees.
