Vocal Behavior of the Elusive Purple Frog of India (Nasikabatrachus sahyadrensis), a Fossorial Species Endemic to the Western Ghats
Figure 3
Vocal interaction in Nasikabatrachus sahyadrensis.
Shown are two 23-s segments of a vocal interaction that occurred between two males (A and B) while held in close proximity in captivity. The letter above each series of calls corresponds to the male that produced the call. In instances of call overlap, the first letter indicates the male that called first and was subsequently overlapped by the male indicated by the second letter. Times correspond to the time between the onset of the overlapped male's call and the onset of the subsequent overlapping call. Inset: Shown here are details of the two shaded regions with the calls of male A and male B illustrated in different colors. The first and second 23-s segments of this interaction are included as audio files in the Supporting Information for this article (Audio S2 and Audio S3, respectively).
