My biggest reason for disagreement with the idea that it is magnetic alignment is that the other animals use it in both directions. Migratory birds fly North and South equally well. Deer graze North and South. Polarity makes no difference which direction they are facing. If the fox is using magnetic alignment it should have equal results North and South. Because the fox has a tremendous difference in success to the south, it must be some other factor influencing the outcome.
And it does not matter if they are flying North, south, east or West, because they are using their ears and only their ears. The fox is using his ears and eyes together. If the Fox only used his ears he would be close to equally successful in all directions. Because the Fox is experiencing almost zero success in all but 1 direction there must be a factor that influences the other 3 direction negatively, or 1 direction positively. I see the sun glare as a far more likely explanation for negative effect, than magnetic alignment for a positive effect..Owls catch mice under the snow, at night and do so without the aid of clear vision or sonar, but rather by focusing on the origin of a sound.
