With its long decurved bill and brown body, the curlew resembles the kiwi. So when the first Polynesian settlers arrived, they may have applied the word kiwi to the newfound bird. [11] The bird's name is spelled with a lower-case k and, being a word of Māori origin, normally stays as kiwi when pluralised. [12] [failed verification]
The southern brown kiwi, like all kiwi, has two functioning ovaries, however only the left oviduct functions, allowing eggs from both ovaries to pass through. It is a monogamous species and once paired up, they will defend their territories with warning calls. The size of their territory is between 4.9 and 43 hectares (12 and 106 acres).

The eggs laid by the North Island ...

Some birds make use of teamwork while hunting. Predatory birds hunting in pairs have been observed using a "bait and switch" technique, whereby one bird will distract the prey while the other swoops in for the kill. Social behavior requires individual identification, and most birds appear to be capable of recognizing mates, siblings, and young.
The Okarito kiwi is a monotypic species, i.e. there are no recognised subspecies. [4] The genus name Apteryx stems from the Greek "without wings". [6] Originally assumed to be the same species as the Southern brown kiwi A. australis, DNA testing shows that the possible split off from this species was 8.2 million years ago, and the split from their closest relatives, the Northern Island brown ...
