We analyzed the reports of Antarctic and Sub-antarctic birds in South American Countries according to scientific papers and gray literature. Forty-eight species were found, and they were observed to occur over oceanic and/or coastal areas of the countries surveyed. Chile was found to present the highest number of seabird species (39), followed by Brazil (38). Species that were less frequently found were Pygoscelis adeliae, Thalassoica antarctica, Pagodroma nivea, Pachyptila salvini and Pterodroma inexpectata, and these were observed only in a single country each. Diomedea exulans, D. epomophora, Thalassarche melanophris, Macronectes giganteus, Fulmarus glacialoides, Pachyptila desolota and Oceanites oceanicus were the seabird species most frequently observed, and were found in six out of the seven countries analysed. Of all species found, three are considered endangered species, eight are considered vulnerable, another eight are considered near threatened, according IUCN. AVES MARINAS ANTÁRTICAS Y SUB-ANTÁRTICAS EN AMÉRICA DEL SUR: UNA REVISION. Analizamos registros de aves marinas antárticas y sub-antárticas en países de América del Sur (Argentina, Brasil, Chile, Ecuador, Perú, Uruguay y Venezuela) en publicaciones cientíicas, disertaciones, tesis y libros. Se registraron cuarenta y ocho especies, observadas sobre áreas oceánicas o costeras de los países estudiados. Chile presentó el mayor número de especies migratorias que anidan en la Antártida (39), seguido por Brasil (38). Las especies observadas con mayor frecuencia fueron Diomedea. exulans, D. epomophora, Thalassarche melanophris, Macronectes giganteus, Fulmarus glacialoides, Pachyptila desolota y Oceanites oceanicus; las cuales fueron reportadas en seis de los siete países analizados. Asimismo, las especies con menor frecuencia fueron Pygoscelis adeliae, Thalassoica antarctica, Pagodroma nivea, Pachyptila salvini y Pterodroma inexpectata, observadas apenas en uno sólo de los países analizados. Entre las especies registradas, tres son consideradas ...
