a-f. Box plots of the mean values for each measured acoustic parameter (not accounting for individual identity). Panel a) duration, b) intercall interval, c) peak frequency, d) low frequency, e) delta frequency, f) intensity. Error bars represent 95% CI. Different letters above box plots indicate significant differences between contexts. Where sex differences were found plots are split into two panels: F = female, M = male.
