Migratory birds have been long known to be able to detect magnetic fields to help navigate their annal routes. The mechanism itself, however, was a mystery. Nature Magazine has published a study revealing that the European robin can actually SEE magnetic fields through the use of proteins situated in the eye's light-sensitive cells! The study also disproved the theory that iron-based cells in the birds’ beaks were the reason for detecting magnetic fields.
