        NOVA | The Mysteries of Optic Flow

        Watch how birds navigate in a series of experiments in this video from NOVA. They use a technique known as optic flow to determine distance and speed. This helps them keep a safe distance from other objects and land gracefully at their destination. Understanding optic flow may help us build better navigation systems for our own flying machines or help us design better structures to deter birds from flying into them.
