the evidence is strong. It seems that birds navigate by using a protein in their eyes that lets them “see” Earth’s magnetic fields.
The fancy eye protein is called Cry4. And it’s clustered in an area that receives a lot of light. Birds use the cryptochromes in their eyes to orient themselves by detecting magnetic fields
These findings come courtesy of two new papers – one studying robins, the other zebra finches.
