Upland Moa

The Lesser Megalapteryx or Upland Moa (Megalapteryx didinus) was a species of ratite bird endemic to New Zealand. Ratites are flightless birds with a sternum without a keel. They also have a distinctive palate. The origin of these birds is becoming clearer as it is now believed that early ancestors of these birds were able to fly and flew to the southern areas that they have been found in. It was the last moa species to become extinct, vanishing around 1500; possibly, some isolated populations managed to persist until about the early 19th century.
