Each fall, North American monarchs travel from their summer breeding grounds to overwintering locations. East of the Rocky Mountains, monarchs travel up journey north monarch an astonishing 3, miles to central Mexico, whereas the shorter migration west of the Rockies is to the California coast.

Journey North engages students and citizen scientists around the globe in tracking wildlife migration and seasonal change. Participants share field observations across the northern hemisphere, exploring the interrelated aspects of seasonal change. In addition to monarchs, Journey North tracks the migration of several other species, including hummingbirds, robins, gray whales, whooping cranes, bald eagles, and tulips. Skip to main content.

Monarch butterfly migration is the phenomenon, mainly across North America, where the subspecies Danaus plexippus plexippus migrates each summer and autumn to and from overwintering sites on the West Coast of California or mountainous sites in Central Mexico. Other subspecies perform minor migrations or none at all. This massive movement of butterflies has been called "one of the most spectacular natural phenomena in the world". The monarchs begin their southern migration from September to October. Eastern and northeastern populations, up to , monarch butterflies, migrate at this time. Originating in southern Canada and the United States, they travel to overwintering sites in central Mexico. The butterflies arrive at their roosting sites in November. They remain in their roosts during the winter months and then begin their northern migration in March. No individual butterfly completes the entire round trip. Female monarchs lay eggs for a subsequent generation during the northward migration. Similarly, the western populations migrate annually from regions west of the Rocky Mountains to overwintering sites on the coast of California. Not all monarch populations make major migrations. Monarchs migrate short distances in Australia and New Zealand.

Monarch Watch. Chip Taylor, Monarch Watch []. It is generally the fourth generation that begins where we started this paragraph, migrating through the central and southern U.

In northern regions of the U. Spring is still months away. The colder temperatures of January and February provide ideal weather for planning pollinator habitats and reading the news from monarch overwintering sanctuaries in Mexico and along coastal California. Where monarchs are present, Journey North wants to hear from you. If you live in the southwest and southeast of the U. Monarchs are still being observed periodically in these areas.

Trees on which to cluster are one of the most important elements of the sites. Local governments are considering legislation to provide habitat for migrating monarchs. Overwintering monarchs in California have shown to have a slight preference to roost on native species but will also consistently choose introduced eucalyptus species, even when native species are present. Archived from the original on April 22, Chip Taylor, Monarch Watch []. Further information: Animal navigation and Sun compass in animals. This evidence led researchers to conclude that changes in muscle function afforded migrating monarchs the ability to fly farther and use their energy more efficiently. Washington, D. In Mexico, monarchs roost in oyamel fir forests, which occur in a very small mountainous area in central Mexico. Article Talk. Scientific American. Normally during the breeding season, the ratio of males and females is roughly the same, but during the migration the ratio is skewed toward males. The migration of the Monarch butterfly is documented and studied during annual butterfly counts.

Kronforst et al. With UV-light being allowed to enter the flight simulator, eastern migratory monarchs consistently oriented themselves south. The exception would be the desert locust, Schistocerca gregaria : it was reported once in that individual swarms were seen migrating from the Arabian peninsula over 5, km 3, miles to the west coast of Africa in seven weeks. Roosts of thousands were observed in southern regions of North America. Tagging and recapture allows the determination of the total population of monarchs. The second, third and fourth generations return to their northern breeding locations in the United States and Canada in the spring. This proposed mechanism is called a sun compass. There are many organizations and programs that exist to promote the preservation of the monarch and its migration. Retrieved December 22, Laws and regulations regarding the protection of the overwintering sites and habitat override the interests of land owners, farmer' cooperatives and local governing bodies. They remain in their roosts during the winter months and then begin their northern migration in March.
