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 meat as a food source and for its feathers, which were used to make highly valued pieces of clothing. Kakapo were also occasionally kept as pets. The kakapo is critically endangered; as of August 2018, the total known adult population was living individuals, all of which are named. Because of the introduction of predators such as cats, rats, ferrets, and stoats during European colonisation, the kakapo was almost wiped out. Conservation efforts began in the 1890s, but they were not very successful until the implementation of the Kakapo Recovery Programme in 1995. Most kakapo are kept on two predator-free islands,
