Fig. 2. Echolocation calls emitted by Eptesicus bottae in a range of different situations. (1) Search phase call, (2) another search phase call emitted prior to a capture sequence, (3) an approach phase call, (4) a call from the middle of a terminal buzz and (5) a call from the end of a terminal buzz. For each call oscillograms (upper panels), spectrograms (middle panels –1024 Hanning window, 97% overlap) and power spectra (lower panels) are illustrated.
