The origin and evolutionary history of the kiwi

The English name of the kiwi is kiwi. This bird is known as the national bird of New Zealand and is known as the "symbol of New Zealand". It belongs to the class of snipe ostriches, also known as wingless birds. It is the most primitive bird among snipe birds. It can be traced back to the First World War. There are only three species of kiwi in the world, all of which are distributed in New Zealand, Oceania. They are called brown kiwi, great-spotted kiwi and small-spotted kiwi.

Kiwis are rare birds unique to New Zealand, and the Smithsonian National Zoo is one of only four zoos in the world outside New Zealand that breeds kiwis. In 1975, the Smithsonian National Zoo successfully hatched a kiwi. This 30-year-old kiwi is still meeting visitors in the zoo's aviary.

Several species of kiwi that have been confirmed are flightless, nocturnal birds. They all live in New Zealand and are endemic to the country. The North Island brown kiwi is also listed as endangered by the International Union for the Conservation of Nature and Natural Resources.

The kiwi is a first-level protected animal in the appendix of the Washington Convention.
