Individual "mollymawk" albatrosses of the genus Thalassarche are occasionally recorded ashore, and even attempting to breed, within colonies of species of the same genus outside their normal breeding ranges (click here for a review).  Here is a photo gallery of six of these vagrant mollies, with thanks to the photographers.
