I wonder what happens when the Earth's magnetic poles reverse, like they have in the past. On average, it happens every 200k - 300k years, so animals have experienced this many times. I'm guessing there's a lot of initial confusion, but that they become accustomed to the new orientation, once they associate a direction with whatever sense they have of the magnetic field.
