Supplemental Figure 1. A figure showing the distribution of call RL and background noise levels by individual ID. Lactating females are denoted with circles, other age/sex classes are denoted by squares. Supplemental Figure 2. A plot showing the k-means density plots by call RL for high and low amplitude clusters.
