Resumen
Los despliegues agonísticos en los monos aulladores (género Alouatta), no solo se han observado a través de las vocalizaciones sino también mediante exhibiciones físicas. Este estudio describe la observación de campo del comportamiento agonista de dos machos Alouatta caraya adultos al exhibir su garganta a los observadores en la ciudad de Pilar, Paraguay. Este comportamiento no se vinculó con el rascado, la petición de acicalamiento o un comportamiento termorregulador. Dadas las adaptaciones para la conservación de la energía descritas en Alouatta, esta exhibición de garganta podría servir como un comportamiento agonístico ritualizado, reemplazando las vocalizaciones altamente energéticas por comportamientos posturales. Este comportamiento solo se ha visto en grupos urbanos habituados y por ello se necesita más investigación para comprender el contexto social y la significancia de este comportamiento en poblaciones urbanas y rurales de A. caraya. Esta es la primera instancia registrada de tal exhibición en especies de Alouatta.
