Recolonisation of Heard Island by the King Penguin, Aptenodytes patagonica.

Abstract

A census conducted at Heard Island (latitude 5°S, longitude 73°E) in February and March by the 1963 ANARE Heard Island expedition showed that the island had been recolonized by the King Penguin, Aptenodytes patagonica, within the previous eight years. More than 100 King Penguins, of which 23 pairs were breeding, were seen. The two largest colonies were at Spit Bay, but breeding was also observed at three other beaches. Laying was estimated to begin in late November and continue at least until early March. Possible causes of the present increase in numbers of the King Penguin at Heard and other islands are discussed.
