Abstract

Diel patterns of vocal activity are key to understanding the behavioral dynamics of species. Although vocalizations occur throughout the day, many bird species tend to concentrate most vocalizations at two specific times: the dawn chorus and the dusk chorus, daily periods of high vocal activity present in most passerines. Currently, acoustic detection tools are used to facilitate and make more effective the monitoring and detection of species. In the present study, we determined daily vocal activity patterns for the song and calls of the Apolinar’s Wren (Cistothorus apolinari) and tested the effectiveness of the R software package 'monitoR' as an acoustic detection tool. There were differences in the accuracy of vocalizations analyzed using monitoR (81% for calls) (27% for songs), for the analyzed vocalizations, the Apolinar's Wren shows two peaks of vocal activity that are consistent with the morning chorus and the evening chorus but follow different daily patterns. The monitoR tool proved to be effective for calls but not for a complex vocalization such as the wren song
