The impact of avian predator‐scavengers on King Penguin Aptenodytes patagonicus chicks at Marion Island
While ashore King Penguins Aptenodytes patagonicus are fed upon by a guild of five predator‐scavenger seabirds. During the winter (April‐October) male Southern Giant Petrels Macronectes giganteus killed an estimated 6430 (11.2%) of Marion Island's King Penguin chicks, although most birds only s...
