The use of leafy twigs for rain cover by the pygmy chimpanzees of Wamba
- 45 Downloads
Pygmy chimpanzees (Pan paniscus) of Wamba sometimes put leafy twigs on their bodies in a rain. In some cases, those twigs seemed to be effective against the rain-impact. There is no record that common chimpanzees (Pan troglodytes) show the same behaviour, but similar or more elaborate use of twigs as rain cover is recorded among orang-utans (Pongo pygmaeus).
