Migration is the relatively long-distance movement of individuals, usually on a seasonal basis. 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, wildebeest migrating annually for seasonal grazing 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. Migration can be either obligate, meaning individuals must migrate, or facultative, meaning individuals can choose to migrate or not.
