Daughter chimpanzee learning to call with her mother

We can see two wild chimpanzees, a mother and her daughter, producing the typical face expression associated with their characteristic call used to communicate between distant groups in the Budongo forest, Uganda. Here, the daughter chorused with the mother's call to respond to another group of chimpanzees from the same community. In my research on the development of vocalisations in chimpanzees we showed that chorusing with the mother may help young ones to learn when and how to respond during vocal exchanges.
