Use of drinking tools by wild chimpanzees (Pan troglodytes) and the context in which the tools were used were studied at Bossou, Republic of Guinea, West Africa. During the middle to late dry season and early wet season liquids are available occasionally in the holes of trees. Chimpanzees drank water or sap using a leaf (or fiber) as a sponge or spoon. When the chimpanzees were on the ground, they tended to use one of a few kinds of soft, hairless leaves, if they were available nearby. Females… 
Leaf-tool use for drinking water by wild chimpanzees (Pan troglodytes): acquisition patterns and handedness
The results provide the first detailed description of the acquisition process underlying leaf-tool use along with the accompanying patterns of handedness, while also being the first to provide comparisons of the development of different forms of tool use within the same wild chimpanzee population.
Tool-use for drinking water by immature chimpanzees of Mahale: prevalence of an unessential behavior
Between-site comparisons revealed that chimpanzees at drier habitats used tools for drinking water more frequently and in a more “conventional” manner, and variations could not be explained by ecological conditions.
Pestle-pounding behavior of wild chimpanzees at Bossou, Guinea: A newly observed tool-using behavior
A new type of tool-using behavior was observed in a group of wild chimpanzees (Pan troglodytes verus) at Bossou, Guinea, which appears to have been invented recently and has since spread widely throughout the group as a habitual one.
Leaf-folding Behavior for Drinking Water by Wild Chimpanzees at Bossou, Guinea
The observation revealed a third method of using leaves: the chimpanzees folded a leaf in the mouth as in paper-folding and put it into the container for capturing water, showing chimpanzees' ability to find a suitable material and modifying it into a useful tool.
Acquisition and Transmission of Tool Making and Use for Drinking Juice in a Group of Captive Chimpanzees (Pan troglodytes)
The present study examined the acquisition and transmission of tool making and use in a group of chimpanzees in an outdoor compound and found that the chimpanzees showed high selectivity with regard to tool type.
Fluid dipping technology of chimpanzees in Comoé National Park, Ivory Coast
This is the first time that water dipping behavior with sticks has been found as a widespread and well‐established behavior across different age and sex classes and communities, suggesting the possibility of cultural transmission.
Behavioral Repertoire of Tool Use in the Wild Chimpanzees at Bossou
An exhaustive comparison of seven long-term wild chimpanzee studies identified regional variations in 39 behavioral patterns that cannot be explained by differences in local environmental conditions.
Leaf-folding behavior for drinking water by wild chimpanzees (Pan troglodytes verus) at Bossou, Guinea
Infant chimpanzees showed more frequent observations of others using leaves before trying to drink water with leaves, suggesting that both observation and trial and error might be necessary for the acquisition of this tool-use behavior.
The Tool Repertoire of Bossou Chimpanzees
This chapter aims to present globally the Diversity of tool-use behaviors of the Bossou chimpanzees, highlighting their age-class, sex, and temporal distribution, the diversity of domains in which they are observed, and patterns of hand use during tool manipulation.
Use of Leaves for Drinking Water
The longitudinal record of manufacture and use of leaf tools for drinking water is described, highlighting the learning process underlying the acquisition of the skill and highlighting the degree of laterality evident in both immature and mature performers.

Preliminary calculations of the age‐specific birth rate for wild female chimpanzees were based on demographic records from a long‐term study at Bossou, Republic of Guinea, and found that the lifetime reproductive success must be less than the minimum reproductive success required for continued survival of the population.
