“Imagine being blindfolded and then taken hundreds of miles from home -- perhaps even to another country across the sea. And then suddenly having the blindfold removed and, despite not having the slightest idea where you are, racing home at top speed. Even if home is six hundred miles away. That is not normal. Just like the superpowers of comicbook heroes, the homing instinct of pigeons is something that scientists cannot explain. They have tried over the years, with theories about magnetic fields and the sun, but no one has satisfactorily managed it.

It is a strangely comfy superpower though. The pigeon is not on a mission to save the world. It just wants to go home. From the age of six weeks, pigeons can be taught to "home" to the loft from which they make their first flight because they understand that is where they will find food, water and company. Pigeons can be picky in their journey -- they do not like to fly at night or to cross water, often flying along the coast to find the shortest point at which to cross a body like the English Channel. but they are ultimately single-minded in simply wanting to get back to where they belong. Amid the horrors of wartime, this longing has a particular resonance.”
