We describe the first observation of a predation attempt by Nigerian-Cameroon chimpanzees (Pan troglodytes ellioti) on Preuss’s red colobus (Procolobus preussi) in the Ebo forest, Cameroon. The activity, which was observed for 15 min, primarily involved 1 chimpanzee and 1 red colobus individual, with a further 2 chimpanzees observing the event. Although the behaviour was interrupted when we were detected by the chimpanzees, we believe that this is the first recorded observation of hunting behaviour in Nigeria-Cameroon chimpanzees.
