in animal behaviour, communal area in which two or more males of a species perform courtship displays. Lek behaviour, also called arena behaviour, is found in a number of insects, birds, and mammals. Varying degrees of interaction occur between the males, from virtually none to closely cooperative dancing. Females visit the lek briefly to select mates and to copulate, but they do not form lasting pair bonds with the males
