It sounds like a natural Augmented Reality HUD. Interesting...

  Not nearly as interesting as the fact that it only happens in the one eye, not the other!

    It probably happens in both eyes but only the left hemisphere (handling input from the right eye) is wired to do the pattern recognition needed.

      I wonder if there's any "left-eyed" robins out there.

    The reason it works is because it's only one eye. The brain compares the two eyes, and if it sees a difference it knows it's because of the magnetic field. If it was both eyes it would not be able to tell the difference between magnetic images and regular ones.
