Title: Use of leaves for drinking water Authors: Sousa, Cláudia
Abstract: The use of leaves for drinking water is a widespread
tool-use behavior among chimpanzees. Although this tool-use
behavior is widely described as the use of leaf sponges, it can
actually be found in three different forms: leaf sponges, leaf-
folding, and leaf spoons. Among the chimpanzee community of
Bossou, we can observe all three forms, albeit in different
frequencies. Here I describe the longitudinal record of
manufacture and use of leaf tools for drinking water,
highlighting the learning process underlying the acquisition of
the skill. The degree of laterality evident in both immature and
mature performers is also presented here. The use of leaves for
drinking
