The vocal repertoire and the daily calling activity of the Yellow-breasted Barbet (Trachyphonus margaritatus)

Abstract

Abstract The Yellow-breasted Barbet ( Trachyphonus margaritatus ) is a group-living and chorusing bird species. However, its vocal repertoire remains poorly described. In this study, we measured the acoustic features of four distinct vocalisations as well as the daily calling activity of barbets at 11 roosting cavity sites. We found that bird’s peak of calling activity is early in the morning and at the end of the day. The cohesion calls and group vocal displays were the most common vocalisations. Moreover, cohesion calls were often used before the start of a group vocal displays which suggests a function in the intra-group cohesiveness.
