Taxonomy
Apteryx australis is based on Greek and Latin. Apteryx means "A-" without "pterux" wings, and "australis" from "auster" the south wind, and "-alis" relating to. Hence Relating to the south wind is the meaning of Australis, not Australia. The Southern Brown Kiwi belongs to the Kiwi family and it is a ratite, and a member of the order Struthioniformes. Like all ratites, its sternum has no keel, it is flightless, and it has a distinctive palate.
The Southern Brown Kiwi is divided into two subspecies:
- A. a. australis, South Island Brown Kiwi, with a population of approximately 7,000 birds is found on the South Island of New Zealand. A disjunct population, near Haast, called the Haast Brown Kiwi (not to be confused with Apteryx haastii), is rare (with only about 250 specimens left) and is characterised by its rufous plumage.
- A. a. lawryi, Stewart Island Brown Kiwi is relatively common (20,000 birds) throughout its range, with about 17 birds per square kilometre. Its feathers are streaked lengthwise with reddish-brown.
