Abstract

Males engaging in same-sex competition can assess the strength of an opponent by means of behavioural display in order to avoid escalated interactions. There is no published record of male–male fighting with lethal consequences in eastern grey kangaroos, Macropus giganteus. The combat between two males reported here had a fatal outcome.
