in NZ they are NZ rehab birds. In Australia and everywhere else they are Australian birds.Not directly related but it's something that just crossed my mind: what is the captive population of Little Blue Penguins made up of?

they are not supposed to be bred from (they are mostly the birds which cannot be released - a lot of them have missing limbs, have damaged bills, are blind, etc), but it does happen here and there.Cool, thanks.
So is there a mixture of subspecies in New Zealand zoos then? Do they breed?

With regards to taxonomy there has always been a lot of dispute. In the 1970s there were deemed to be six subspecies based on distribution and appearance (novaehollandiae in Australia, and five within New Zealand). One of these, the distinctive White-flippered Penguin, was variously treated as a subspecies or as a full species (E. albosignata), and was finally demoted to just a colour morph. Later when DNA testing entered the field it was found that the results did not support the multi-subspecies view, but that the differences were probably simply clinal. For the most part, in Australasia the species has been treated as monotypic for most of the 2000s.
It was noted from the mitochondrial DNA that there were two clades, one in Australia and southeastern NZ (in the Otago area), and the other everywhere else in NZ. However the genetic differences, while clear, were still not considered enough to separate them even as subspecies. Different studies have shown varying opinions on the distinctiveness of their calls and outward appearance.
This current paper ("proving" the two clades are actually two distinct species) is another part of the above. It is from the same start-point (and does include more than just the mtDNA so is more comprehensive), and ends in completely the opposite direction. The current trend in taxonomy is splitting, but it remains to be seen if this split is generally accepted. I'm sticking with one species for now.
the HBW/IBC like to have it both ways. They say "Validity of races questioned, and current evidence points to a N–S cline" but also "Six subspecies recognized".That is very interesting, thanks.
I usually go off hbw.com when looking at bird subspecies, and they list six subspecies for Little Blue Penguins (Little Penguin (Eudyptula minor) | HBW Alive). However it's nice to hear some further/other information.![]()
