Nobody knows how homing pigeons work. They're still in use by some navies and still a mystery to us. It's been theorized that they just have an amazing sense of direction, but if you transport them in a dark container, spinning them all around and upside down in the process, then release them, they can still find their way home.
Luca Turin became acquainted with a scientist who wondered if they are somehow "connected" to their home base by a kind of invisible string or band. He had an idea that you could test this theory by, instead of just moving the pigeons, moving their home. In his proposed experiment, you'd raise the pigeons on a ship, take them away, and then relocate the ship. Would the pigeons fly back to the ship, or back to the original port?
Turin thought this was a fascinating experiment, and via his connections he managed to secure funding for it. But, to his great disappointment, the scientist declined.
Was he afraid the results wouldn't be interesting?
