Moa were nine species of now-extinct 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) while the smallest, the bush moa, was around the size of a turkey. Estimates of the Moa population when Polynesians settled New Zealand circa 1300 vary between 58,000 and approximately 2.5 million.
