abstract
Eighty-eight food samples were collected from grey-headed albatrosses Diomedea chrysostoma at the Prince Edward Islands. Fish and cephalopods were the two main prey components of the diet, the former being predominant. It was not possible to identify most of the fish prey but the most commonly eaten squid were Kondakovia longimana and Histioteuthis eltaninae with the mass of individual squid varying between 13 g and 1 815 g. Whereas the diet was similar to that of grey-headed albatrosses at Iles Crozet it contrasted with that of birds at South Georgia which had a higher proportion of cephalopods and crustaceans in their diet. Differences between the cephalopod beaks recorded in casts and regurgitations are discussed.
