A Comparison Among the Calls of Four Penguin Species
In this paper we analyze the calls of four penguin species ( Aptenodytes patagonica , Eudyptes chrysolophus , Pygoscelis papua , Pygoscelis antarctica ) recorded in the Antarctic. We analyze the sonogram and power spectrum of the calls and make a comparison among different species in call duration,...
