Every fall, a magical event takes place—the annual monarch migration to Mexico. Perhaps traveling over your own head right now—or clustered by the hundreds in a nearby tree—monarchs are on the move. By instinct alone, they migrate to the mountains in Mexico where they've never been before.
We look on with wonder:
- How do the monarchs know when to go to Mexico?
- How do they know which way to fly?
- How fast, how far, and how high do they travel?
- Why do monarchs migrate?
Travel with the monarchs this fall. Find out what's known about these migration mysteries, and how much more we can discover.
