One example of a structural adaptation is a bird's long beak that helps it catch more food. Another is the ability of a desert plant to store water. An example of a behavioral adaptation is animals migrating to a warmer climate. An adaptation is a genetic change, called a mutation, that makes an organism better able to live in its environment.
