Echolocation clicks of free-ranging Chilean dolphins (Cephalorhynchus eutropia)

Research output: Contribution to journalArticle

DOI

Abstract

In this paper, evidence is provided that Chilean dolphins (Cephalorhynchus eutropia) produce ultrasonic echolocation clicks of the narrow-band high-frequency category. Echolocation clicks emitted during approaches of the hydrophones consisted only of narrow-band (rms-BW: 12.0 kHz) single pulses with mean centroid frequencies of about 126 kHz, peak frequencies of 126 kHz, and a 20 dB duration of 82.6 µs. The maximum received level measured exceeded 165 dB re 1 µPa. In addition, high repetition-rate buzzes were recorded during foraging behavior (click interval: 2 ms), but no whistles or calls with tonal components were detected
