dc:abstract During the breeding season reproductively active South American sea lion males (Otaria fivescens) compete aggressively against other males to defend a position along the shoreline, where most females group (Campagna and Le Boeuf 1988a). Vocalizations are a conspicuous component of male behavior: high pitched calls (HPC) are highly directional sounds used at the beginning of a fight, barks are given during the establishment and maintenance of territories and in relation to female defense, and growls occur mainly during interactions with females (Fernlndez-Juricic et al, 1999). Despite the importance of vocal displays, it is not known if males adapt their communication signals to different social contexts. Vocal rates (number of calls per individual per unit time) are considered a good indicator of vocal behavior, since temporal and spatial variations in vocal rates may convey different messages in pinnipeds (Schusterman 1977 , Shipley and .....
