Buller’s Shearwater, Puffinus bulleri, is commonly seen on U.S. Pacific pelagics. It is easy to identify because of it’s distinctive m-shaped marking on the upper wings.
It breeds on islands off New Zealand and is a transequatorial migrant, moving into the northern Pacific.
The species has been classified as vulnerable but it seems to be in good shape now that feral pigs have been eradicated from its main breeding islands.
