Historically, up to 80 different taxa have been described by different researchers; most of these were incorrectly identified juvenile birds. This expanded taxonomy elevated many established subspecies to full species, but was criticised for not using, in every case, peer reviewed information to justify the splits.
Since then, further studies have in some instances supported or disproved the splits; a 2004 paper analysing the mitochondrial DNA and microsatellites agreed with the conclusion that the Antipodean albatross and the Tristan albatross were distinct from the wandering albatross, per Robertson and Nunn, but found that the suggested Gibson's albatross, Diomedea gibsoni, was not distinct from the Antipodean albatross.
The North Pacific albatrosses are considered to be a sister taxon to the great albatrosses, while the sooty albatrosses are considered closer to the mollymawks.
The taxonomy of the albatross group has been a source of much debate.
Both the British Ornithologists' Union and the South African authorities split the albatrosses into four genera as Nunn suggested, and the change has been accepted by the majority of researchers.
The albatrosses are usually regarded as falling into four genera, but there is disagreement over the number of species.By 1965, in an attempt to bring some order back to the classification of albatrosses, they were lumped into two genera, Phoebetria (the sooty albatrosses which most closely seemed to resemble the procellarids and were at the time considered "primitive" ) and Diomedea (the rest).Though there was a case for the simplification of the family (particularly the nomenclature), the classification was based on the morphological analysis by Elliott Coues in 1866, and paid little attention to more recent studies and even ignored some of Coues's suggestions.A breeding season can take over a year from laying to fledging, with a single egg laid in each breeding attempt.A Laysan albatross, named Wisdom, on Midway Island is recognised as the oldest wild bird in the world; she was first banded in 1956 by Chandler Robbins.
