Abstract：
:Twenty-three king penguins (Aptenodytes patagonicus) from Macquarie Island were tracked by satellite during the late incubation period in 1998-1999 to determine the overlap of the foraging zone of king penguins with an area to be declared a marine protected area (MPA) near the island. While all penguins left the colony in an easterly direction and traveled clockwise back to the island, three penguins foraged in the northern parts of the general foraging area and stayed north of 56 degrees S. The remaining 20 penguins ventured south and most crossed 59 degrees S before returning to the island. The total foraging area was estimated to be 156,000 km2 with 36,500 km2 being most important (where penguins spent > 150 hr in total). North-foraging penguins reached on average 331 +/- 24 km from the colony compared to 530 +/- 76 km for the south-foraging penguins. The latter traveled an average total distance of 1313 +/- 176 km, while the northern foragers averaged 963 +/- 166 km. Not only did the penguins spend the majority of their foraging time within the boundaries of the proposed MPA, they also foraged chiefly within the boundaries of a highly protected zone. Thus, the MPA is likely to encompass the foraging zone of king penguins, at least during incubation.
