Migratory Birds: Aviator navigator
When you go to the library or the shopping center, you rely on landmarks—shops, street names, etc—to tell you which way to go. Some people’s sense of direction (or lack of it), still allows them to miss a turn or end up passing their destination.
That’s exactly why migratory birds gets the honor of being the animal with the most amazing ability in the world: the ability to fly great distances and not get lost. Researchers believe these birds are born with a form of synesthesia that allows them to see the Earth’s magnetic lines that normal people can’t. It may sound a little far-fetched, but a theory is better than no theory at all.
