During the breeding season, adult male bullfrogs, Rana catesbeiana, establish territories from which conspecific males are aggressively excluded. Stereotyped postures, approaches, and physical encounters all function in the defense of such areas. It is proposed that the highly polygamous social system present in this species creates an intense intermale competition for females, and that possession of a territory directly influences an individual male's chances of successful mating.
