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 of the kakapo until George Gray of the British Museum described it from a skin in 1845. As the Māori had done, early European explorers and their dogs ate kakapo. In the late 19th century, the kakapo became well known as a scientific curiosity, and thousands were captured or killed for zoos, museums and collectors. Most captured specimens died within months. From at least the 1870s, collectors knew the kakapo population was declining; their prime concern was to collect as many as possible before the bird became extinct. In the 1880s, large numbers of mustelids (stoats, ferrets and weasels) were
