| Migratory birds Many birds, especially those that migrate, can use the "Earth's magnetic field to stay their course during long flights. Scientists still aren't sure how they do it, but one recent study suggests birds might have a form of synesthesia that lets them "see" the planet's magnetic lines as patterns of color or light that is overlaid on their visual surroundings. Humans must rely on familiar landmarks or the sun's position to locate North, and many can't even manage that.
