Which Monarchs Are Migrating from Mexico? Click on map to enlarge. Not all monarchs migrate to the Mexican sanctuaries in the fall. Some monarchs can be found during the winter in northern Mexico, along the coasts of the U.S. Gulf States, and along the California coast. Here is an animated clip of the spring 2000 monarch migration. The red triangles show where monarchs over-wintered that year. As you watch the wave of migration move across the continent . . . Do you think the pattern suggests that all the monarchs are coming from Mexico? Why or why not? Do you think coastal monarchs that wintered along the Gulf Coast are also migrating north? Why or why not? The picture is still incomplete. We need hundreds of additional observations to help us clarify the pattern. Please help us gather data. National Science Education Standards Use data to conduct a reasonable explanation. Although men and women using scientific inquiry have learned much about the objects, events, and phenomena in nature, much more remains to be understood.
