Salvin's Albatross

Salvin's albatross (Thalassarche salvini) or Salvin's mollymawk, is a large seabird that breeds mainly on the Bounty Islands of New Zealand, with scant amounts on islands across the Southern Ocean. A medium-sized mollymawk, it was long considered to be a subspecies of the shy albatross.

The adult bird has a silver-grey crown. Its face, upper throat, and upper mantle are grey, and its back, upperwing, and tail are grey-black. It has a white rump and underparts with a black thumbmark on underwing and black narrow leading and trailing edges on the wing and black wing tips. Its bill is pale grey-green with a pale yellow upper ridge, and a bright yellow tip on the upper mandible, and a dark spot on the tip of the lower mandible. The juveniles have more extensive grey areas and a blue-grey bill with black tips on both mandibles. It can be distinguished from the Chatham albatross by its larger size and grey bill, and from the shy albatross by the greyer head. Such differences can be difficult to pick out at sea, however, and this explains the under-representation of this species in at-sea surveys.
