Albatross

Albatrosses, of the biological family Diomedeidae, are large seabirds allied to the procellariids, storm-petrels and diving-petrels in the order Procellariiformes (the tubenoses).

Species
Current thinking divides the albatrosses into four genera. The number of species is a matter of some debate. The IUCN and BirdLife International among others recognise the interim taxonomy of 22 extant species, other authorities retain the more traditional 14 species, and one recent paper proposed a reduction to 13:
 * Great albatrosses (Diomedea)
 * Wandering Albatross  D. exulans
