Chimpanzees in Bwindi-Impenetrable National Park, Uganda, Use Different Tools to Obtain Different Types of Honey

Abstract

Evidence of tool use for foraging for honey by chimpanzees in Bwindi-Impenetrable National Park, Uganda, is reported. These are the first records of tool use by chimpanzees in this region of the Albertine Rift. Tools of two types were found at sites of bee activity. Chimpanzees apparently use small stick tools to forage for the honey of a stingless bee [Meliponula bocandei (Trigonidae)] that nests in tree cavities and also in subterranean holes. They use significantly larger, thicker tools to assist in foraging for honey of African honeybees (Apis mellifera)
