Bird's-Eye View May Include Magnetic Fields

BoredStiff writes "Heard on NPR and reported in ScienceDaily: a study finding that migratory birds may be able to 'see' magnetic fields. The report comes from a current study by a research group from Oldenburg, Germany. They found that migratory birds use their visual system to perceive the reference compass direction of the geomagnetic field: 'Sensory systems process their particular stimuli along specific brain circuits. Thus, the identification of what sensory system is active during magnetic compass orientation, provides a way to recognize the sensory quality utilized during that specific behavior.'"

So what happens if the magnetic field changes?

What happens if the magnet field flips, or drops completely for few millenia, as is speculated has happened before and will likely happen again?

If they can see the field lines, though, this may not be the case.

This is quite unlikely, given that there are no such things as magnetic field lines.
