ScienceAlert:

The mystery behind how birds navigate might finally be solved: it's not the iron in their beaks providing a magnetic compass, but a protein in their eyes that lets them "see" Earth's magnetic fields.

These findings come courtesy of two papers - one studying robins, the other zebra finches.

The fancy eye protein is called Cry4, and it's part of a class of proteins called cryptochromes - photoreceptors sensitive to blue light, found in both plants and animals. These proteins play a role in regulating circadian rhythms.
