Migration
Migration is when a group of animals travel long distances in search of food, to give birth to young or to avoid bad weather. There are two main types of migration. Most migrations are seasonal but some are nomadic or unpredictable. When animals migrate to the seasons the migration happens at a certain time every year. Animals migrate because seasonal changes can have a huge effect on animals. The food supply can be extremely scarce so it is harder to find food. The weather can make it hard for new born animals to survive as well. Nomadic migrators migrate when the food supply runs out in one place, so they move to another feeding ground and then when the food supply runs out there, they will move again. This means the same animal will probably never come to the same feeding ground twice in their life. Some animals' journeys are extremely dangerous and long, although it is worth it when they get to their destination. Humpback Whales are an example of migrators.
