Southern and northern Buller's albatrossesThalassarche bulleri
The southern (Thalassarche bulleri bulleri) and northern (T. b. platei) Buller's albatrosses are increasingly considered to be two different species. Both are endemic to New Zealand, but the former breeds on the Snares and Solander islands, whereas the latter breeds off Chatham and Three Kings islands. The two Buller's albatrosses are very difficult to distinguish at sea, and the distribution presented here shows them together. Additionally, at-sea identifications of Buller’s albatrosses may be confused with the Salvin's and grey-headed albatrosses.
