The Giant MOA: New ZeaLand Extinct FlightLess Bird

Before to the arrival of Polynesian settlers, the Giant Moa had been living in what is now New Zealand for at least 40,000 years. They only laid one or two eggs at a time and it took these birds 10 years to grow to maturity
Its only predator was the Haast´s Eagle, the largest of these birds that ever existed.

Dinornis were the tallest bird that ever lived, with females standing up to 3.6 m (12 ft) tall and weighing between 230–240 kg (510–530 lb) and 278 kg (613 lb).
There were two species:  the North Island Giant Moa (Dinornis novae zealandiae) and the South Island Giant Moa  (Dinornis robustus

The Māori still hunted them at the beginning of the fifteenth century, driving them into pits and robbing their nests. 
Also, some birds became extinct due to farming, when the forests were cut and burned down and the ground was turned into arable land. 
All Giant Moa species had been extinct for 300 years  before the arrival of European settlers.
