There is a deep hole in a tree trunk and within is a tasty dollop of sweet, nutritious honey. It's a worthwhile prize for any animal skilled or clever enough to reach it, and chimpanzees certainly have both of these qualities. But the solutions they find aren't always the same - they depend on cultural traditions.
Chimps from the Sonso community in Uganda are skilled at the use of sticks and unsurprisingly, they manufacture stick-based tools to reach the honey. Chimps from the Kanyawara community in a different part of Uganda have never been seen to use sticks in the wild. Instead, they bring their considerable leaf-based technology to the fore, using leaves a sponges to soak up the hidden honey.
