Many of New Zealand's bird species are endemic to the country, that is, they are not found in any other country. Of the species breeding in New Zealand before humans arrived, 71% were endemic. [1] Some species are not fully endemic, but are breeding endemic, in that they breed only in New Zealand, but migrate or range elsewhere.
The kiwi is a national symbol of New Zealand.. The animals of New Zealand, part of its biota, have an unusual history because, before the arrival of humans, less than 900 years ago, the country was mostly free of mammals, except those that could swim there (seals, sea lions, and, off-shore, whales and dolphins) or fly there ().
New Zealand's forest ecosystems for example are being considered as the second most endangered of the world, with only 7% of the natural habitat remaining. [12] A male brown kiwi. Eighty per cent of New Zealand's biota is endemic. New Zealand's biodiversity exhibits high levels of endemism, both in its flora and fauna.
The Australasian swamphen, Porphyrio melanotus, is a communal gallinule and a member of the rail family, Rallidae. [2] The Rallidae family is a diverse group of non-passerine birds (birds that do not belong to the order Passeriformes, which includes perching birds and songbirds) with primarily terrestrial habits, characterised by relatively short wings and strong, often elongated bills.
The birds of New Zealand evolved into an avifauna that included many endemic species found in no other country. As an island archipelago, New Zealand accumulated bird diversity, and when Captain James Cook arrived in the 1770s he noted that the bird song was deafening.
The species has between 5 and 6 billion base pairs of DNA sequence, nearly twice that of humans. [16] The tuatara has been protected by law since 1895. [17] [18] Tuatara, like many of New Zealand's native animals, are threatened by habitat loss and introduced predators, such as the Polynesian rat (Rattus exulans).
