The Cape Gannet Morus capensis is an endemic seabird to southern Africa, breeding on offshore islands off Namibia and South Africa (Harrison 1985). After breeding, dispersal takes place as far as Mozambique, rarely Tanzania, on the east coast of Africa, and to the Gulf of Guinea on the west (Harrison 1985). However, vagrant birds have been reported in Victoria, Australia (Venn 1982) and on the Atlantic coast of South America, in the Argentinean Patagonia and the Beagle Channel (Bergkamp 1995, Ramírez 1996) at the southern tip of South America.
