Penguins perceive variations of source- and filter-related vocal parameters of species-specific vocalisations.

ABSTRACT: Animal vocalisations encode a wide range of biological information about the age, sex, body size, and social status of the emitter. Moreover, vocalisations play a significant role in signalling the identity of the emitter to conspecifics. Recent studies have shown that, in the African penguin (Spheniscus demersus), acoustic cues to individual identity are encoded in the fundamental frequency (F₀) and resonance frequencies (formants) of the vocal tract. However, although penguins are known to produce vocalisations where F₀ and formants vary among individuals, it remains to be tested whether the receivers can perceive and use such information in the individual recognition process. In this study, using the Habituation-Dishabituation (HD) paradigm, we tested the hypothesi
