Marvels of Monarch Migration
About this time of year in North America, a fascinating phenomenon occurs: monarch butterflies commence their migrations. Those west of the Rocky Mountains head over to the California area. Monarchs in South America have a migration as well, but those are not understood very well. Some of these insects stay put.

Several critters make long journeys, and have various methods of navigation . Both migration, and the life cycle of monarchs, defy evolutionary thinking. via GIPHY I don't know how it's done, but volunteers help track monarchs , especially since their habitats are dwindling and efforts are being undertaken
