Abstract: The foraging ranges of six female and four male Adélie penguins breeding at Bechervaise ... Island near Mawson Station (Mac. Robertson Land) were determined by satellite tracking, using the ARGOS ... system. Birds were tracked over four foraging trips (by 2 females and 4 males) during the incubation ... birds were feeding chicks.
