Flocking is an instinctive behavior that follows simple rules and does not require central coordination, but whose results can be astounding: bird migrations over thousands of miles, for example, or complex structures like termite mounds. The advantages of a flock versus a single animal are that a group of animals is stronger, better protected and can hunt or feed better.
