Robin :Some birds can sense the Earth’s magnetic field and orientate themselves with the ease of a compass needle. This ability is a massive boon for migrating birds, keeping frequent flyers on the straight and narrow. This incredible sense is closely tied to the sense of  vision. Birds like the European robins can literally see magnetic fields as patterns of light and shade, or even colour, superimposed onto what they normally see, because of the special molecules in the retina
