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
Flightless cormorant bird eventually became flightless. Indeed, wings trapping air among flight feathers are likely to have been a disadvantage to the cormorants which dive from the surface. However, since their discovery by man, the islands have not remained free of predators: cats, dogs, and pigs have been introduced to the islands over the years. In addition, these birds have no fear of humans and can easily be approached and picked up. In the past, introduced feral dogs were a great threat to the species on Isabela, but they have since been eradicated from the island. Future introduction of rats or cats
