South Island robin
species of bird
The South Island robin (Petroica australis; also known in Māori as the kakaruai) is a sparrow-sized bird found only in New Zealand, where it has the status of a protected endemic species. The birds are sparsely distributed through the South Island and Stewart Island / Rakiura, although the distribution is not continuous. The nominate, and the Stewart Island robin (P. australis rakiura) are the two subspecies. The species is closely related to the North Island robin (formerly P. australis longipes, now considered a distinct species), and also to the extremely rare black robin (P. traversi) of the Chatham Islands.
Taxonomy
The South Island robin has two subspecies: P. australis australis, the nominate form, and P. australis rakiura, the Stewart Island robin. These subspecies do not overlap in their distributions. The North Island robin (P. longipes), the tomtit (Petroica macrocephala), and the black robin (Petroica traversi) in the Chatham Islands are closely related species. P. traversi seems to be a Chatham Island derivative of P. australis, although the position of the most recent common ancestor has yet to be determined. The family Petroicidae of Australasian robins has a total of 49 species, mostly in Australia, New Zealand, and New Guinea.
Fossil record
There is molecular phylogenetic evidence to suggest two waves of immigration by the Petroica genus from Australia.
The public source identifies “South Island robin” as species of bird. This brief keeps that definition visible, then builds a research path around South, Island and robin.
Why this record matters
A short description can identify a subject without explaining its stakes. For “South Island robin”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 16, 2026. The linked authority identifier is Q1051396. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
