Northern Royal Albatross
Diomedea sanfordi
The northern royal albatross is typically about 115 cm (45 in) tall, weighs 6.2 to 8.2 kg (14–18 lb), and has a wingspan from 270 to 305 cm (106–120 in). The juvenile has a white head, neck, upper mantle, rump, and underparts. There is dark speckling on the crown and rump. Its lower mantle and back are white with more black speckling than the crown, and it has dark black-brown upper wings with white flecks on its coverts. Its tail is white with a black-brown tip, as are its underwings. There is a black band behind the leading edge of its wings between the carpal joint and the tip.

Snowy Albatross
Diomedea exulans
The plumage varies with age, with the juveniles starting chocolate brown. As they age they become whiter. The adults have white bodies with white and black wings. Males have whiter wings than females, with just the tips and trailing edges of the wings black. The snowy albatross is the whitest of the wandering albatross species complex, the other species having a great deal more brown and black on the wings and body, very closely resembling immature wandering albatrosses. The large bill is pink, as are the feet.
