Ant dipping and meat eating by wild chimpanzees in the Kalinzu Forest, Uganda

New evidence of ant dipping and meat eating by chimpanzees was recorded in the Kalinzu Forest, Uganda. We found stems and branches at the nests of dri ver ants, Dorylus molestus, just after chimpanzees had left the spot. Fecal samples also revealed that chimpanzees sometimes ate driver ants. The conf iguration of stems and branches and the condition of holes at the driver an t's nests suggested that chimpanzees used them as wands to dip for ants. Th e frequency of ant dipping and length of wands may be more related to cultu ral rather than ecological factors. Although hunting was not seen, we found chimpanzees eating a blue monkey and a redtail monkey. In both cases, they ate meat and leaves alternatively, and shared meat with each other.
