Before humans settled in New Zealand, it would have been an extremely noisy place! Large tracts of lush native bush supported an incredible variety of bird life. As they evolved, wings became unnecessary for some birds, as they had no natural predators to fly away from. As a result, several of New Zealand's native birds became flightless, including the kakapo parrot, the kiwi, the takahe, and the world's largest bird, the (now extinct) moa.
