With 16 extant species and 15 extinct ones, what country in the world is home to the most flightless birds?

As an island isolated from the world, New Zealand has unique fauna. In particular, because there are very few ground predators there, many of the nation's birds lost their ability to fly over the years. As a result, they thrived in a land of plentiful food, warm weather, and very few threats.
