FIGURE 6. The advertisement call of a male C. exedrus paratype (SAMA R64762) recorded at ambient temperature of 18.4°C on 21 April 2009 (1830 hr, by SJR): (A) oscillogram (relative amplitude vs. time in s) of three typical notes and (B) a 2 s audiospectrogram (frequency in kHz vs. time in s) from the middle of a 60 s, 44-pulsed call (D, relative amplitude vs. time in s). Note (C) the corresponding power spectrum (Fast Fourier Transformation; relative amplitude vs. frequency in kHz) of a single note, depicting a fundamental (lowest) frequency of 2.3 kHz and the dominant (emphasized) frequency of 4.7 kHz.
