dc.description.abstract
We analysed whether South American sea lions
(Otaria flavescens) varied the syntax or arrangement
of vocalizations (the order in which calls were produced) according to diVerent social contexts.
Three male calls that formed a progression of
increasingly aggressive displays (growl<bark<highpitched call) were studied in a breeding colony at
Península Valdés. We found that: (a) growls and
barks had higher probabilities of emission than
high-pitched calls, (b) vocal bouts generally were
initiated by growls, (c) the transitions most likely to
occur were growl-bark and bark-growl, and (d) the
number of male-male agonistic interactions (highpitched call after growl, bark after growl) and the
number of neighbour males (growl after highpitched call) aVected some transitions between call
types. The baseline vocal display of males consists
of a sequence of growls and barks given in suc- cession (e.g., growl–bark–growl–bark), which can
incorporate high-pitched calls during highly
aggressive male-male interactions. Vocal arrangement variations could be a strategy to modulate
agonistic behaviour during vocal displays and to
increase the chances of being detected in noisy
breeding colonies.
