Papaya Fruit Sharing in Wild Chimpanzees at Bossou, Guinea

Food sharing between non-kin of wild chimpanzees has been reported since Goodall's initial study in 1960. Chimpanzees are often reported to share meat. On the other hand, plant food sharing are rarely reported, except for studies from Gombe and Mahale where chimpanzees were formerly provisioned for research and observed sharing sugar canes and bananas.
Most studies discuss food sharing with reference to maintenance of alpha status, social relationships and cooperative hunting. Some studies suggest a relationship between food sharing and female choice, but this claim lacks sufficient evidence6, 16 and recent studies have tried to refute it with substantial data.
I observed the cases of papaya fruit sharing by wild chimpanzees at Bossou Guinea. The papaya is the largest fruit that Bossou chimpanzees can obtain. Here I discuss the food sharing with reference to mating behaviors.
