In many acoustic surveys, vocalizations of sequential focal (target) animals are counted by a trained listener or automated detection by a computer algorithm, preceded or followed by noise reduction techniques to isolate the signal of interest from background noise ( Aide et al., 2013 1. Identifying individual species vocalizations in the natural environment is challenging, however, because animals often vocalize in groups in the midst of biological and anthropogenic noise sources that can interfere with their own perception of sounds as well as an observer's ability to document and count these sounds.
