Solution:

The South Island giant moa -Dinornis robustus- is a member of the moa family. It was a ratite and a member of the order Dinornithiformes. The Dinornithiformes 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 in which they have been found.

It lived on the South Island of New Zealand, and its habitat was the lowlands (shrubland, duneland, grassland, and forests). Along with members of the moa family, the South Island giant moa went extinct due to predation from humans in the centuries following human colonization.
