Acoustic stimuli and parameters used in this study. (a) Oscillograms and spectrograms of the seven synthetic stimuli used in the labeling component of this study and the heterospecific call (PC100) presented for comparison. Dashed lines indicate the beginning and ending frequencies of the conspecific call (PC00, blue) and arrowheads indicate the duration of the PC00. (b) A stylized oscillogram (Upper) and spectrogram (Lower) of the synthetic túngara whine are shown along with the seven acoustic parameters used to construct stimuli in this study.
