Breeds in New Zealand and ranges across the temperate South Pacific to the Humboldt Current; uncommon off Chile and Peru. All ages have thick black leading edge on the underwing, wider than the narrower black edge on larger Salvin’s and Chatham Albatrosses, and narrower than on stockier Gray-headed Albatross, a bird of cold subantarctic waters. Adult Buller’s has gray hood with silvery white crown and thick yellow edges on black bill. First-year birds have a paler gray hood, a pale bill with black “seam lines,” and black subterminal band; mostly like adult in 3 years. Compare with immature of larger Salvin’s Albatross.
