Development of aggressive vocalizations in male southern elephant seals (Mirounga leonina): maturation or learning?
Summary Vocalizations are an important component of male elephant seal agonistic behaviour. Acoustic and behavioural components of vocalizations emitted during agonistic contests show gross differences between young and old males, but the variation with age depends on the specific feature.
