Oh dear, there are multiple species called "toroa" on this list, and I didn't realise. Ok, let's make sure that we get the differences between them really clear!
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.
We have already covered the Antipodean albatross, aka toroa.
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.
Based on the species information from NZ birds online article about the Antipodean albatross, pictured above, the Gibson's albatross is actually a subspecies - and I have already drawn two birds with Gibson's markings.
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.
