Migration can vary significantly in duration depending on the species, distance traveled, and specific routes taken. For some birds, migration can last several weeks as they travel thousands of miles between breeding and wintering grounds. Other animals, like certain fish or mammals, may migrate over shorter distances and complete their journeys in a matter of days. Overall, the length of migration is highly variable and influenced by ecological factors and seasonal changes.
1. Most migration is over a short distance.2. Migration occurs in steps.3. Long-range migrants usually move to urban areas.4. Each migration produces a movement in the opposite direction (although not necessarily of the same volume).5. Rural dwellers are more migratory than urban dwellers.6. Within their own country females are more migratory than males, but males are more migratory over long distances.7. Most migrants are adults.8. Large towns grow more by migration than by natural increase.9. Migration increases with economic development.10. Migration is mostly due to economic causes.ravenstein-s-laws-of-migration
Permanent migration refers to the long-term relocation of individuals or groups from one country or region to another, with the intention of settling there indefinitely. This type of migration often involves obtaining legal residency or citizenship in the new location. Factors driving permanent migration can include economic opportunities, family reunification, political stability, or escaping conflict and persecution. Unlike temporary migration, which is usually for a specific duration, permanent migration signifies a commitment to a new home.
Depends on what you mean... but I'll try.There is migration, chain migration, forced migration, voluntary migration, net-in migration, net-out migration, immigration, emmigration, countermigration.These are Human Geographic terms by the way. That makes about 9 types of migration.
The long migration typically refers to the annual journey of certain animal species, particularly birds and mammals, as they travel long distances between breeding and wintering grounds. This phenomenon is driven by seasonal changes in climate and food availability. Notable examples include the migration of monarch butterflies, wildebeests in the Serengeti, and various bird species such as the Arctic Tern. These migrations are crucial for the survival of the species and are often fraught with challenges, including predation and habitat loss.
Who you would call a migration expert would probably depend on which species migration you want information about. A person who specializes in, say, wolves and their migration might be totally different from aperson who specializes in the migration of, say, seagulls.

one reason for this cycle would be one of dan perez's plan of not stying in a place too long.

Called "drought" - if it lasts long enough them migration or death.
