Heading south for the winter
One monarch butterfly flies by. Then another and another. As they fly the butterflies seem to float in the sky. They make beauifut shadows on the ground below. They seem to be everywhere. In fact there are so many butterflies that the groups look like beehives in the trees. And when they fly the sound of 150 million monarchs wings in the world where you can hear the sound of butterflies wings moving.
The migration
Every year millions and millions of monarch butterflies migrate from the U.S.A and Canada. They go to a place high in the mountains of Mexico. There they can escape from North America's day. But what's really amazing is that the butterflies make the trip only once. Somehow they know exactly where to go.
The Effect on People
After the butterflies arrive in Mexico people gather to watch. The effect on people is amazing . Young and old men and women locals and people from far away everyone is smiling and friendly. It's as though the butterflies encourage people to be their best.
