Curr Biol. 2000 Sep 7;10(17):R634-6. doi: 10.1016/s0960-9822(00)00661-8.

Abstract

How do emperor penguins find their mates on a featureless ice flow, packed at densities of ten animals per square meter? A recent study has revealed how use of their 'two-voice' calls enables emperor penguins to locate their mates and chicks under some of nature's most extreme conditions.
