What do animals typically do during migration?

During migration, animals typically travel long distances to find food. This behavior is often driven by seasonal changes, where animals move from areas that may be depleted of resources to areas that offer abundant food sources. For instance, many bird species migrate to warmer climates during winter months to access insects, fruits, and other food resources that become scarce in colder regions. This long-distance travel ensures that they can survive and reproduce effectively by finding food-rich environments.

Other options do not accurately represent the primary purpose of migration. While social behaviors may occur amongst migrating animals, such as flocking, it is not the main characteristic associated with the migration process. Storing food in home territories is more typical of species that have a sedentary lifestyle, rather than those that migrate. Changing mating calls might occur in specific contexts, but it is not a defining behavior associated with migration. Thus, traveling long distances to find food is the most relevant and accurate answer.
