Animal migration is the relatively long-distance movement of individuals, usually on a seasonal basis. It is a ubiquitous phenomenon, found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The trigger for the migration may be local climate, local availability of food, the season of the year or for mating reasons] To be counted as a true migration, and not just a local dispersal or irruption, the movement of the animals should be an annual or seasonal occurrence, such as birds migrating south for the winter, or a major habitat change as part of their life, such as young Atlantic salmon leaving the river of their birth when they have reached a few inches in size. PLS SHOW US ONE OR GROUP OF ANIMALS VISITING YOUR COUNTRY AND DESCRIBE WHEN IT'S COMING AND WHERE FROM.

The Monarch butterfly is the only butterfly that makes northwards and southwards migrations. They migrate between their summer home in southern Canada and the United States and their wintering ground in Mexico. This photograph shows a Monarch feeding on a Butterfly Bush (Liatris) in early September in Ontario in preparation for its southward migration.
