Crevices and cracks in logs are searched for insects, and nests are robbed for eggs and chicks. Sometimes they use rocks for breaking open tough fruits. When food is plentiful, a large group of chimps assembles for a feast. Adult males drum on the buttress roots of trees or on the ground and other chimps join in a loud hooting chorus. This noise can be heard a long way off, attracting other chimps as well.
Chimps seem to get most of their water from the fruit they eat.
They rarely drink and when they do, they dip one hand into the water and lick it. They also crush leaves into a 'sponge' squeeze the water into their mouth. Conservation concern In West Africa, chimps are now very rare because most of their forest habitat has been chopped down to make room for farming. Although chimps are still quite common in other parts of Africa, in some areas people enjoy eating chimpanzees and many are killed for food. These days, logging companies are moving into new areas of rainforest to exploit them for timber.
