How do chimpanzees build their nests?
We’re not the only primates to enjoy tucking ourselves up for a good night’s sleep; every day, chimpanzees and other great apes carefully construct nests to keep them safe and warm until morning. A chimp’s nest is much more like our own beds than the nests of other animals; it consists of a firm foundation, a springy ‘mattress’ layer and a soft top layer. Baby chimps sleep in their mother’s nest, but they must be taught this important skill when they’re weaned.
An average chimp nest measures about 1.5m (4.9ft) in length and just under 1m (3.3ft) across. Nests are built in different trees every day. It’s thought that this might be for hygiene reasons, avoiding a build-up of waste and parasites that could make them ill.
Scientists now believe that high-quality sleep may have enabled humans to evolve
