Trivia: Which country has no native land mammals except bats?
Morocco
New Zealand
Mongolia
Japan
The correct answer is New Zealand
So why is this answer correct? : Before humans arrived, New Zealand’s islands belonged mostly to native birds, many of which remained flightless because of the lack of predators. (Case in point: New Zealand’s national bird, the kiwi.) Unfortunately, many native birds are now extinct or at risk — in part because of rodents and other mammals introduced to the region by humans, including rats, weasels, and possums.
