Diet of feral goats and feral pigs on Auckland Island, New Zealand
The diets of feral pigs and feral goats shot on the main Auckland Island in 1989 are described from analyses of stomach and rumen contents. Feral goats ate at least 50 species of plants, but only three, Metrosideros umbellata, Chionochloa antarctica, and Durvillea antarctica made up over 50% by dried weight of the food eaten. Feral pigs ate a mixed plant and animal diet, of which plants made up 61% of the diet, with the megaherb Anisotome antipoda being the largest dietary item at 38% by dried weight.
