Many of New Zealand's birds are endemic to the country, that is, they are not found in any other country. Endemic species differ to native or indigenous species, in that native / indigenous species have generally, and historically, migrated to a region or country and become established over a long period of time, whereas endemic species, essentially have only ever inhabited the region or country they were first discovered in. Approximately 71% of the bird species breeding in New Zealand before humans arrived are widely accepted as being endemic.
