Abstract

During 13 visits to the State of Rio Grande do Sul, Brazil outside of the breeding season. stomachs were collected from 144 dead and randomly selected first-year Magellanic Penguins Spheniscus magellanicus and their contentsanalyzed. Cephalopods were an important item in the diet and were found in76% of the stomachs, averaging five cephalopod beaks per stomach. The following cephalopods were identified from the remains: Illex argentinus, Histioteuthis sp., Loligo sp.. L. sanpaulensis, L. plei, Argonauta nodosa and one specimen of family Cranchiidae. Smaller numbers of fish and fish otoliths(less than cone per stomach); a few Hydrozoa, Isopoda and Salpa sp. were also found. Parasitic Nematoda were recorded in 80% of the stomachs. Many ofthe cephalopods were small and were probably planktonic. Maximum size of prey were larger than those reported from the breeding season.
