The Nene (pronounced "nay-nay") is a land bird and a variety of Hawaiian Goose. It has adapted itself to life in the harsh lava country by transforming its webbed feet into a claw-like shape and modifying its wing structure for shorter flights. Hunting and wild animals all but destroyed the species until they were protected by law and a restoration project was established in 1949.
