King Penguin Aptenodytes patagonicus


Sounds and Vocal Behavior


The primary form of communication in king penguins is a two-voice system that is produced by the syrinx, a two-part organ located where the bronchi join. King penguin chicks identify their parents by an acoustic signal. Each syllable has two harmonic series, one which is strongly modulated in frequency and the other in amplitude. Previous work showed that only one syllable of the call is needed for the chick to identify the calling adult. Both the frequency and modulation pattern of the syllable and play a role in the call identification. (T Aubin; P Jouventin, 2002)
