Agreement on the Conservation of Albatrosses and Petrels

UPDATED. Vagrant Grey-headed Albatrosses visit Black-browed Albatross colonies in the Falkland Islands (Islas Malvinas)*

Mollymawk albatrosses Thalassarche spp. occasionally turn up as vagrants on islands in the Southern Ocean, usually in breeding colonies of congeners, as reported from time to time in ACAP Latest News (click here).  Some of the birds occupy nests and there a few examples of pairing with the species breeding in the visited colony.

Mollymawk species recorded in this way include Black-browed T. melanophris (Marion Island), Indian Yellow-nosed T. carteri (Marion), Salvin’s T. salvini, (Diego Ramirez, Gough and Kerguelen) and White-capped T. steadi (Bird (South Georgia (Islas Georgias del Sur)*), Prince Edward).  The Grey-headed Albatross T. chrysostoma has also been reported in the literature as a vagrant in the Falkland Islands (Islas Malvinas)*, with a banded individual on West Point Island seen every year from 1952 to 1956, and another record in 1969.

Eight more recent records of vagrant Grey-headed Albatrosses from the Falkland Islands (Islas Malvinas)* are reported here by island locality.
