Current thinking divides the albatrosses into four genera. The number of species is a matter of debate. The IUCN and BirdLife International recognise 22 extant species (listed below), ITIS recognise 21 (the 22 below minus T. steadi), and one recent paper proposed a reduction to 13 (indicated in parentheses below), comprising the traditional 14 species minus D. amsterdamensis.
Today, we are looking at the Gibson’s wandering albatross/toroa, and we still also have to cover the Salvin’s albatross or mollymawk/toroa, too.
DOC also lumps them together in their article – and given that we have so many birds to cover, we are going to call this one done (because it is!) and move on to the next.
