From turtles to albatrosses, many species migrate long distances, normally in a quest for food or mates. But exactly how these animals manage to stay on track while traversing thousands of kilometers across land and sea has managed to evade scientists and remained a mystery. A new study has, however, been able to show that manipulating the magnetic field to which a migrating bird is exposed correspondingly alters its direction of travel.
