Ecstatic display calls of the Adélie penguin honestly predict male condition and breeding success
Abstract The Adélie penguin (Pygoscelis adeliae) breeds in large, noisy Antarctic colonies and has evolved a communication system of complex intra- and inter-sexual visual and vocal behaviours. The Ecstatic Display Call (EDC) given by males whilst at the breeding colony is composed of introductory b...
