The moa were nine species of flightless birds and endemic to New Zealand. The two largest species of moa was Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 m in height and weighed about 230 kg. All these nine species of moa were the only wingless birds. Moa fed on a range of plant species and plant parts, including fibrous twigs and leaves taken from low trees and shrubs. The moa’s only predator was the massive Haast’s eagle. After that humans were hunted moa’s.
