Feeding biology and energetics of King Aptenodytes patagonicus and Gentoo Pygoscelis papua Penguins at sub-Antarctic Marion Island
Includes bibliographies. Adaptations of penguins for pursuit diving have resulted in reduced foraging ranges, compared to volant seabirds. However, their classification as inshore, offshore or pelagic foragers, based on rates of food provisioning to chicks, still has merit as a framework around whic...
