Researchers have spotted a group of 53 cells within pigeons' brains that respond to the direction and strength of the Earth's magnetic field.
The question of how birds navigate using - among other signals - magnetic fields is the subject of much debate.
These new "GPS neurons" seem to show how magnetic information is represented in birds' brains.
However, the study reported by Science leaves open the question of how they actually sense the magnetic field.
David Dickman of the Baylor College of Medicine in the US set up an experiment in which pigeons were held in place, while the magnetic field around them was varied in its strength and direction.

Quite interesting. I would also suspect that there *are* humans that have these 'sensors' in their brains as well. I know my wife and daughter always know where they are. My wife even when drunk. I refer to her as my personal navigation system.
And yes, she occasionally tells me where to go.

My wife sometimes tells me where to go too...but it usually isn't directional instructions she offers, but rather more of a destination, as in 'GO TO ...!!!!'
