- Diomedea sanfordi
Identification
- Length around 110 cm, wingspan around 3 m
- Head and body white
- Scapulars with brown markings
- Tail white except usually black tips on some feathers
- Upperside of wing entirely black except for a small white wedge at the base of the leading edge
- Underside of wing white except for narrow black trailing edge and black wedge on leading edge of primaries
- Bill pale pinkish with black cutting edge
- Eyes black
- Legs pale pinkish
Juvenile very similar, but in first plumage has dark barring on rump, dark spots on crown, and may have pale edges to coverts on upperwing.
Similar Species
Southern Royal Albatross is larger, has a white leading edge to upperwing (narrow in juvenile, getting wider with age) and black on leading edge of underside of primaries is only a narrow line.
The species formerly in Wandering Albatross (Snowy Albatross, Tristan Albatross, Antipodean Albatross, and Amsterdam Albatross) all lack the black cutting edge on the bill.

Distribution
Breeding takes place entirely in New Zealand waters; most of the population in the Chatham islands, and small numbers in Auckland Island (where hybridization with Southern Royal Albatross have been registered) and at Taiaroa Heads, Otago Peninsula (by far the easiest place to see them).
Outside of breeding season, they occur circumpolar in the south seas, in areas where the surface temperature is from 6 to 20 degrees C. This takes them to coasts of such areas as Chile, Argentina and Angola, with vagrancy in Brazil!
Taxonomy
Formerly considered the same species as Southern Royal Albatross.
Subspecies
This is a monotypic species[1].
Habitat
Breeds on slopes with access to the sea, often near exposed areas to facilitate getting airborne. The breeding grounds often have tussock grass which give some shelter for the wind.
At sea mostly takes dead or dying prey captured within one meter of the surface. They frequently seek out offal from fishing boats but are not known as great ship followers otherwise.
Behaviour
At sea mostly takes dead or dying prey captured within one meter of the surface. They frequently seek out offal from fishing boats but are not known as great ship followers otherwise.
Breeding
Breeding takes place every other year, with a single egg laid in October-November. Hatching happens about 2-1/2 month later, and the young stay on land for another about 8 month. Once they leave the nest, they will stay at sea for 3-4 years before visiting the colony, and it will be another about 4 years before they nest for the first time.
Vocalisation
Known to give a variety of sounds both at breeding grounds and more rarely when interacting with other birds at sea. Sounds given include bill claps.
