Birds of New Zealand Birds of New Zealand The birds of New Zealand evolved into an avifauna that included a large number of endemic species (that is, 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 mix includes species with unusual biology such as the kakapo which is the world's only flightless, nocturnal, lek (competitive display) breeding parrot, but also many species that are similar to neighboring land areas. A process of colonization, speciation and extinction has been at play
Kakapo midden deposits show that the bird was present throughout the North and South Island before and during early Māori times. Māori hunted the kakapo for food and for their skins and feathers, which were made into cloaks. They used the dried heads as ear ornaments. Due to its inability to fly, strong scent and habit of freezing when threatened, the kakapo was easy prey for the Māori and their dogs. Its eggs and chicks were also preyed upon by the Polynesian rat or kiore, which the Māori brought to New Zealand. Furthermore, the deliberate clearing of vegetation by Māori reduced
