Tall Moa Bird of New Zealand

The Moa were nine species (in six genera) of flightless birds endemic to New Zealand.
The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 m (12 ft) in height with neck outstretched, and weighed about 230 kg (510 lb).

Moa belong to the ratite group in the order Dinornithiformes. The nine species of moa were the only wingless birds, lacking even the vestigial wings which all other ratites have. They were the dominant herbivores in New Zealand's forest, shrubland and subalpine ecosystems for thousands of years, and until the arrival of the Māori were hunted only by the Haast's Eagle. It is generally considered that most, if not all, species of moa died out by 1400 AD due to overhunting by the Māori and habitat decline.
