Migration in animals refers to the seasonal movement of a group of animals from one region or habitat to another. It is a behavior observed in various species, including birds, mammals, fish, and insects. Migration typically occurs in response to changes in temperature, food availability, or breeding conditions. Animals migrate to find better resources or suitable environments for survival and reproduction. Some migratory journeys can be extremely long, spanning thousands of kilometers. Migration is an adaptive strategy that allows animals to take advantage of different habitats and maximize their chances of survival.
