Tilly, sweetest chimp !

Seven-year-old Tilly is one of Sanaga-Yong’s sweetest chimpanzees. She and her friends, Shy and Xeko, are sometimes bullied by some of the young adolescents in their social group, but mostly they manage to avoid conflict and invest their time in playing. Here Tilly has a play face, as she’s tickled by a friend. Photo by Jacques Gillon
