ABSTRACT

In penguins vocalizations are believed to be of primary importance in communication (Pettingill 1960, Stonehouse 1960, Boersma 1974, Spurr 1975, Scheich 1980a,b, Jouventin 1982). A detailed study of the Mutual Display call of the Emperor Penguin Aptenodytes forsteri revealed significant individual variation (Robisson et al. 1993). Such individuality of the calls is proposed as being particularly important for southern species which live in large dense colonies and in areas lacking landmarks. The barren habitat increases the need for vocal recognition of mates, chicks, and neighbours to locate nesting sites. To date vocal studies have primarily concentrated on these sub-Antarctic and Antarctic species (Stonehouse 1960, Penny 1964, Jouventin 1982, Robisson et al. 1993).
