Polar Shift Causes Bird Fish Deaths?

A new theory has caused a lot of buzz on the Internet, might explain the Bird Fish Deaths worldwide ...  That theory is that some of the bird kills could be the result of a shift in the magnetic field.    The birds rely on magnetic fields for navigation.   The north pole has been shifting by as much as 25 miles per year.  Experts say further testing will need to be done to determine whether the shifting magnetic fields played any part in the animal deaths.
