Dolphins will migrate for warmer waters and to follow food sources. The migration patterns are seasonal, with coastal dolphins migrating from the Northern Atlantic coast to the Southern Atlantic coast in the winter. In warmer coastal regions along Florida, Georgia, Texas and California, most dolphins create home bases and do not leave or stray from these areas.
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food.
