Abstract

The movements of nine breeding adult emperor penguins Aptenodytes forsteri from two colonies, Auster (67° 23′S 64° 04′E) and Taylor Glacier (67° 28′S 60° 54′E), were determined by satellite telemetry on their pre-moult foraging trips. While preparing for their annual moult the penguins travelled for 22–38 days and reached distances of up to 618 km from the colony. Six of the nine tracked penguins were followed to three different moult locations all to the west of their breeding colonies and near other known emperor penguins colonies, such as Kloa Point (66°38′S, 59°23′E) and Fold Island (67°17′S, 59°23′E). Sea-ice conditions changed throughout the tracking period; as the birds travelled north the sea-ice contracted south.
