Feeding area specialization of chick‐rearing Adélie Penguins Pygoscelis adeliae in a fast sea‐ice area
Individual feeding area specialization has been reported for several seabird species. Researchers suspect that this behaviour results in feeding and/or reproductive advantages. Adélie Penguins Pygoscelis adeliae feed in small predictable open waters in a fast sea‐ice area near Syowa Station, Antarct...
