<b>Fig S1. </b>All tested variables showed significant positive correlation with the detection rate by the automatic detector using the non-parametric Spearman’s rank correlation (r =roh) indicating a significant effect on the resulting detection rate (per minute of effort) in each sound file. A) correlation between the minimum number of singers per sound file and the detection rate, B) correlation between the signal to noise ratio (SNR) per sound file and the detection rate, C) correlation between the % of each sound file which included song units and the detection rate.
