Have you heard of any other forms of navigation?
Short answerMany other methods exist, but the proposed pigeon-on-a-board system would not work as described because a restrained homing pigeon cannot fly home and provide a reliable bearing.
NotesIn the closing exchange, a viewer asks about other forms of navigation. A pigeon anecdote shows why a colourful claim needs a workable mechanism. A homing pigeon finds home by flying, whereas a bird strapped to a board cannot perform that behaviour. Even tethering it would more likely lead the bird to a perch than provide a dependable bearing. The answer rejects this particular story without claiming to catalogue every navigational method or dismissing animal navigation.
