Birds found to have magnetic personalities
UC Irvine researchers have found that migrating birds have
chemical reactions in their bodies that react with the Earth’s
magnetic field and keep them on track.
The results of the study, reported in the May 13 issue of Nature
magazine, dispel previous notions that birds relied on chunks of
magnetic material in their beaks or brain to find their way. It is
the first study to reveal how the birds detect fluctuations in
magnetic fields.
Thorsten Ritz, assistant professor of physics and astronomy, and
colleagues used 12 European robins in the experiment. They exposed
them to magnetic fields and monitored their movement.
In the experiment, the birds became confused when the artificial
magnetic field went in a different direction than the Earth’s natural
magnetic field. Because the fields’ fluctuations were so quick, Ritz
found, it is likely they involve magnetically sensitive chemical
reactions.
