The diet of Gentoo Penguins Pygoscelis papua in early winter at Heard Island.


In Gentoo Penguin faecal samples taken from both sides of the Heard Island Spit, the most common prey was Parathemisto gaudichaudii followed by fish. There were significant differences in the diet between the north and south sides of the Spit, only three kilometres apart. The main difference was the presence of Euphausia vallentini in 46.7 per cent of samples from the north side of the Spit and its complete absence to the south. In addition, fish were more commonly taken on the north side and there were significant differences in the species of fish taken.
