Migration, migratory, or migrate may refer to:

Human migration

Human migration Human migration is the movement of people from one place to another, with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another ( ...

International migration International migration occurs when people cross state boundaries and stay in the host state for some minimum length of the time. Migration occurs for many reasons. Many people leave their home countries in order to look for economic opportunities ...

Migration (ecology) Migration, in ecology, is the large-scale movement of members of a species to a different environment. Migration is a natural behavior and component of the life cycle of many species of mobile organisms, not limited to animals, though animal mi ...

Animal migration Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, ...

Bird migration Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and ...
