Adults may forage away from the colony for a day or more before returning to feed their chicks. This is an unnamed form breeding on the Falkland Islands. It is genetically distinct but otherwise indistinguishable from other dark-eyed populations. Two subspecies are recognized. This is the widespread nominate race. It is largely replaced by the light-eyed T. m. impavida on Campbell Island and New Zealand, although some overlap has been reported. Some authors (e.g. IOC, HBW online, Birdlife International) consider Campbell Albatross to be a separate species. Both types occur together on Campbell Island where they may occasionally form mixed pairs. This species was formerly placed in the genus Diomedea, but moved with the other mollymawks into Thalassarche to maintain generic monophyly. Formerly considered "near threatened" the most recent IUCN assessment is "least concern." Canon PowerShot SX50 HS
