The Tiny Kiwi Bird's Colossal Cousin

Judging by their looks, one would never guess that New Zealand's national bird - the tiny flightless kiwi and the colossal African elephant bird that roamed Madagascar until the 17th Century, had much in common. While the kiwi is roughly the size of a modern chicken and weighs between three to seven pounds, the elephant bird loomed a massive ten feet tall, and could weigh as much as 600 pounds! In addition to the difference in size, the two species lived 7,000 miles apart, making any connection between the two almost impossible.
