Abstract:Acoustic communication plays a key role in the life of birds and it is useful in phylogenetic and evolutionary investigations. This study described the structure and function of Polioptila dumicola´s call repertoire in riparian environments from the Mid-eastern of Argentina. Male calls (N=644) were recorded in the field during the pairs nuptial interactions; nests exploration and previously capture of male. Then, specific function was assigned to different calls using standardized methods of acoustic classific… Show more
