Every fall, steady, predictable winds assist one of the world's most spectacular migrations. In
Wild Canadian Weather, we follow a female monarch butterfly as she sets off on an epic journey in early fall, all with the help of a good breeze.
Each autumn, monarchs take to the skies rising up to 1,200 m to reach strong, steady air currents to propel them south — 4,000 km south to Mexico.
