Migration

Migration occurs when living things move from one biome to another. In most cases organisms migrate to avoid local shortages of food, usually caused by winter.

Birds often migrate. The longest known migration is the Arctic Tern, which migrates from the Arctic to the Antarctic and back each year.

Whales, humans, and lemmings are also known to migrate.
