What is migration in mammals?

Migration is a regular seasonal movement of animals from one region to another. In mammals, migration is a strategy to find suitable habitats for food, breeding, and safety. For example, many ungulates, such as wildebeest, migrate long distances to find fresh grazing grounds. Similarly, some carnivores, such as wolves and bears, may travel long distances in search of prey. Marine mammals, such as whales, also migrate long distances for feeding and breeding purposes.
