The vocal behaviour of wild indris inhabiting the area near Andasibe was studied by means of all occurrence sampling. We provide a quantitative overview of the vocal repertoire of Indri indri, describing qualitative contextual information and quantitative acoustic analysis for all the utterances we recorded from adult individuals. Other than the song, the repertoire of Indri indri comprises 8 vocal types uttered by the adults. Future studies are necessary to explore whether vocalisations uttered in different contexts have different functions and how these functions relate to acoustic structure.

Abstract

The vocal behaviour of wild indris inhabiting the area near Andasibe was studied by means of all occurrence sampling. We provide a quantitative overview of the vocal repertoire of Indri indri, describing qualitative contextual information and quantitative acoustic analysis for all the utterances we recorded from adult individuals. Other than the song, the repertoire of Indri indri comprises 8 vocal types uttered by the adults. Future studies are necessary to explore whether vocalisations uttered in different contexts have different functions and how these functions relate to acoustic structure.
