At a primate rehabilitation sanctuary, carers want to encourage young chimpanzees to use foraging tools. Whenever a chimpanzee successfully uses a twig to extract hidden honey, the carer blows a short whistle. At the end of the session, the chimpanzees can exchange their accumulated whistle sounds for chunks of fresh banana.
