New research proposes that Cry4, a light-sensitive protein found in the eye’s retina may be responsible for magnetoreception in birds.
Sensing Longitude Among Birds
A study has shown that the Eurasian reed warbler is able to sense magnetic declination and use that information to determine their migratory flight path.
Animal Navigation Through Magnetoception
Magnetoception is the ability for certain animals to orient themselves based on the earth’s magnetic field.
