Gray-headed Albatross Thalassarche chrysostoma

Rarely found north of cold subantarctic waters; ranges south to pack-ice in summer. Adult has a gray head, thick black underwing margins like much commoner Black-browed Albatross. Immatures look similar to Black-browed overall, but told by black bill that soon develops yellow along top, and often with variable gray hood. Yellow bill edges narrower than the more lightly built Buller’s Albatross, which occurs to the north but is often mistaken for Gray-headed.
