What does it mean to migrate?

Migration refers to the process of moving from one country or region to another, often to settle in a new location. This behavior is commonly observed in various animal species, particularly birds, which migrate to find suitable climates or breeding grounds. The movement is usually seasonal and can be driven by factors such as changes in food availability, climate, and breeding conditions.

While some organisms may enter a dormant state or hibernate during winter, these concepts are different from migration. Adaptation to the environment refers to the process of evolving traits that improve survival in a specific habitat but does not involve movement from one region to another. Therefore, the definition that encompasses the concept of migration most accurately is the one that describes the act of moving and settling in a new area.
