Cameras have revealed how "armed" chimpanzees raid beehives to gorge on sweet honey.
Scientists in the Republic of Congo found that the wild primates crafted large clubs from branches to pound the nests until they broke open.
The team said some chimps would also use a "toolkit" of different wooden implements in a bid to access the honey and satisfy their sweet tooth.
In this case, the chimp fashions a dipping tool to probe the nest.
The study is published in the International Journal of Primatology.
