Why penguins communicate: the evolution of visual and vocal signals

A comprehensive and condensed review of several hundred publications on the evolution of penguin behaviors, particularly signaling, linking genetics and ecology via such behavioral adaptations as nuptial displays.

This exciting work has developed from the authors' many years researching on the behavioral strategies of penguins, such as the unique vocal signatures for individual recognition.

Studies of penguins on islands surrounding Antarctica are presented, fully showcasing the behavioral significance of visual ornaments (mating displays) and how and why penguins behave via adaptive evolutionary explanations.
