Notes on the occurrence and diet of Southern Giant Petrels, Macronectes giganteus in Rio Grande do Sul, southern Brazil. Here we report records of Southern Giant Petrels, Macronectes giganteus on the coast of Rio Grande do Sul, southern Brazil, in the years 1990, 1997-98, and 2007-09. We recorded 26 Southern Giant Petrels, 19 of which were dead on beaches. The remaining seven were observed feeding on a stranded Southern Right Whale, Eubalaena australis in August 1998. Analysis of the stomach contents of eight specimens revealed the predominance of cephalopods and fishes, as well as a high frequency of plastic material. The presence of plastic material in the stomachs of Southern Giant Petrels is evidence of ocean pollution, an issue that deserves attention due to its relevance for seabird conservation.
