The Mystery of the World’s Greatest Butterfly Migration

Season: 7
Eps: 7

The monarch butterfly migration is one of nature’s greatest events. This orange-winged wonder travels up to 4,500 km from all over North America to spend the winter hanging from oyamel fir trees in central Mexico’s mountain forests. But how does an animal with a brain the size of a poppy seed navigate to this one special place?
