The adult Wandering Albatross appears entirely white from a distance. Close up, the fine black wavy lines on the breast, neck and upper back become visible. The bill can vary in colour, but is normally yellowish-pink. The white tail is occasionally tipped with black and the back of the wing changes from black to white with age. A series of plumage phases are passed through as young birds reach full adult plumage, which can take up to nine years. Females are slightly smaller than males.
