The Dual nature of Electro Magnetism, (Monopole) seems the origin of Pigeon homing and animal tracking.
Even Electric charged field photons seems to be the result of the same transformation. (into + and - string photons.) (see images)
All four strings are transformed into Vector bundels leaving the polarized Fermions.
As a consequence, the Earth magnetic field also shows such string radiation differences in special measurements (see"Image)
