Stewart Island kiwi
Unlike other kiwis, the Stewart Island tokoeka does not live alone.  Instead, Stewart Island tokoeka live in families.  The baby kiwis stay with their parents for up to seven years.  They help sit in their parents' younger eggs.  This makes it so much easier to raise eggs that kiwi parents sometimes have two clutches, groups of eggs, each year.  It also goes onto the beach to look for food, which most other kiwis do not do.
