When New Zealand drifted off from Gondwanaland millions of years ago an isolated and unique flora and fauna developed. New Zealand became a perfect place for flightless birds – there was no mammalian competition and birds were able to fill ecological niches not available on other landmasses.
One of the oddest of these flightless birds is the Kakapo – a giant ground living parrot. Nocturnal and corpulent, it has a sad history – responding to a predator-free environment it took to the ground and was once numerous. But when man and other mammals arrived its numbers declined very rapidly. It is unable to defend itself against predators such as rats, cats or stoats, and its habitat is being lost or subtly changed. It has become a very rare and seriously endangered species.
