Southern brown kiwi

The southern brown kiwi or tokoeka (Apteryx australis) is a bird in the family Apterygidae. It lives in New Zealand. This bird does not fly. It runs on the ground.
Appearance
The southern brown kiwi is about 45 cm long. The adult male kiwi weighs about 2.4 kilograms and the adult female weighs about 3.1 kilograms. The birds living on Stewart Island are the largest. It has red-brown feathers and no tail. It has a long, curved beak. The nostrils are at the end of the beak and not up at the top near the rest of its face.
Habitat and food
The southern brown kiwi lives in forests, scrublands, grasslands and up in hills below the Alpine zone.
Before human beings came to New Zealand, tokoeka lived in many parts of the southern and eastern part of the South Island as far north as North Canterbury.
Most southern brown kiwis hide during the day in burrows, areas with plants or hollow trees and look for food at night, but others look for food during the day. They walk along the ground and tap their beaks against it. They eat animals without bones, for example earthworms, insect larvae, centipedes, spiders and weta. Kiwis fight each other over good places to find food.
The kiwi's closest relative is the elephant bird. It lived in Madagascar long ago. Its closest living relatives are the emu and cassowary.
Eggs
Both male and female southern brown kiwi sit on the eggs in the nest. Sometimes other adult kiwi will help too.
Threats
Before human beings came to live in New Zealand, the southern brown kiwi lived all through the south and east of New Zealand's South Island. There are fewer southern brown kiwi today because human beings change the places where they live and because dogs, cats, stoats and other introduced species eat them. To save the southern brown kiwi, some humans take their eggs and chicks and raise them on islands where there are no stoats.
Subspecies
There are two or three subspecies of southern brown kiwi: Everyone agrees that the Fiordland tokoeka (A. a. australis) and the Stewart Island tokoeka (A. a. lawryi) are subspecies. Scientists do not think that the Haast tokoeka (A. a. Haast) is a real subspecies, but the people trying to keep the birds alive decided it was easier to save the birds if they acted as if it were a third subspecies.
History
For years, historians disagreed about where Western scientists found the first kiwi specimen, meaning the first dead kiwi that they brought back to universities for study. The first speciimen is usually the one scientists use as a holotype. The holotype is the individual plant or animal that scientists use for the first formal scientific writeup of a species.
George Shaw from the British Museum wrote the first paper about the kiwi in 1813 in his group of books Vivarium naturae. A friend had brought him the kiwi skin. The friend got it from a ship captain named Andrew Barclay. He was captain of a fighting ship and prisoner transport ship called the Providence. It wasn't clear exactly where the ship captain got it.
In 2019, scientists took a tiny piece of the kiwi skin and did DNA analysis. They found the dead kiwi was most closely related to kiwis from Rakiura, an island south of New Zealand's South Island.
