Mystery How bird migrating to faraway places, even across oceans and continents, is now almost unbreakable.
By observing the robin, scientists get a clue as to how the animals sense the Earth’s magnetic field.
The way a robin senses a magnetic field is similar to how we use a compass to determine north or south. Scientists believe, birds have a kind of “compass” in their bodies.
New research supports this hypothesis after scientists discovered a chemical in the eye that is sensitive to magnetism.
According to Peter Hore, professor of chemistry at the University of Oxford, it is possible that birds “can see” the Earth’s magnetic field, although until now we are not sure how birds perceive this field.
Hore explained, scientists may have found a molecule that allows migratory birds to accurately detect the direction of the Earth’s magnetic field.
“Birds clearly have this ability and use this information to help them determine their direction when migrating thousands of kilometers,” Hurray told BBC News.
