Fifty years ago, millions of chimpanzee lived throughout equatorial Africa. Today, they are listed as endangered. There are only 170,000 to 300,000 left and, with their habitat under constant threat, their numbers are declining rapidly. The eastern chimpanzee range has been reduced to the Central African Republic and Democratic Republic of Congo, western Uganda, Rwanda and western Tanzania. Chimpanzee live in a range of habitats including tropical rainforests, dry woodlands and savannah.
A fascinating fact is that groups of chimpanzee living in different regions have unique behaviours, tools and traditions that are passed down from one generation to the next. They are highly sociable creatures that live in communities of up to 120 individuals. Chimpanzee communicate by using vocalisations, hand gestures and facial expressions.
