In a unique partnership, you can join citizen scientists across North America to track the monarch butterfly's spring migration from Mexico.

Spring migration begins in March. An announcement comes from Mexico when the monarchs are on their way. After living off their fat reserves all winter, tens of millions of monarchs head northward. With just a few weeks to live, they race to produce the next generation.

As the migration progresses from March through June, students predict the path the monarchs travel and map their journey north. They explore what scientists know about migration mysteries, and discover how much more there is to learn. They see the many risks the monarchs face and learn about conservation efforts underway to protect monarchs--on the wintering grounds and at points along the path. Perhaps most importantly, students participate in an annual, international celebration as this delicate sign of spring moves across the continent.
