Phonotactic scores of females to call models varying in call duration (A). Scores were calculated by dividing each control trial by the mean control trial of that female. Each point represents the mean (±SE) of 10 females. The number of notes used in the control trials was 4. Graphs illustrating the phonotactic scores of females to call models varying in call rate (B). Each point represents the mean (±SE) of 10 females. The call rate used in the control trials was 15n/min.
