Group association and vocal behaviour during foraging trips in Gentoo penguins
Abstract In contrast to their terrestrial call, the offshore call of penguins during their foraging trips has been poorly studied due to the inaccessibility of the foraging site—the open ocean—to researchers. Here, we present the first description of the vocal behaviour of penguins in the open ocean...
