Diomedea dabbenena (MGT):occurs in the central South Atlantic Ocean and it currently breeds only on Gough and Inaccessible Islands, since it is extinct in Tristan da Cunha (Olmos, 2008). Geolocation data suggests that 14 non-breeding adults used the southwestern Atlantic during the austral summer and migrated to the southeastern Atlantic and Indian Ocean to the east as far as Australia during the austral winter (Reid et al., 2013).Two male specimens banded on Gough Island in January and October were bycatch in longline fishing in Brazil in RS in October and November, respectively (Neves & Olmos, 2001). Records in Brazilian waters for SP (August),SC (November) and RS (October, November) suggest that the species is more frequent in waters under the influence of the Subtropical Convergence away from the coast of RS (Neves & Olmos, 2001). Museum records date for SC in September and RS in June, September and October (MZUSP specimens).
