A stoat in the Ardennes in Belgium, within its natural range. The stoat (Mustela erminea) was introduced into New Zealand to control introduced rabbits and hares, but is now a major threat to the native bird population. The natural range of the stoat is limited to parts of the Northern Hemisphere.
In New Zealand, the stoat feeds principally on birds, including the rare kiwi, kaka, mohua, yellow-crowned parakeet, and New Zealand dotterel. [44] Cases are known of stoats preying on young muskrats. The stoat typically eats about 50 g (1.8 oz) of food a day, which is equivalent to 25% of the animal's live weight.

Approximately 71% of the bird species breeding in New Zealand before humans arrived are widely accepted as being endemic. [ 1 ] There is also a smaller group of species are not fully endemic, but are breeding endemic, in that they breed only in New Zealand, but migrate or range elsewhere.
This is the list of the birds of New Zealand. The common name of the bird in New Zealand English is given first, and its Māori-language name, if different, is also noted. The North Island and South Island are the two largest islands of New Zealand. Stewart Island is the largest of the smaller islands.
Of these, the rats, ferrets, cats, stoats and dogs have all seriously impacted the New Zealand fauna, driving some species to extinction. [ quantify ] Brushtail possums were introduced from Australia for a fur industry, and deer from Europe as game animals, both seriously damaging the forest habitat of many birds.
The weka, also known as the Māori hen [2] or woodhen (Gallirallus australis) is a flightless bird species of the rail family. It is endemic to New Zealand. Some authorities consider it as the only extant member of the genus Gallirallus. [3] Four subspecies are recognized but only two (northern/southern) are supported by genetic evidence. [4]
In New Zealand English, the word "kea" is both singular and plural. The genus Nestor contains four species: the New Zealand kākā (Nestor meridionalis), the kea (N. notabilis), the extinct Norfolk kākā (N. productus), and the extinct Chatham kākā (N. chathamensis). All four are thought to stem from a "proto-kākā", dwelling in the forests ...
