Very cool, D'stone.
I saw something awesome in the North America series on Discovery. They think foxes have some kind of hard-wired magnetic field understanding. In the winter when there is snow pack, they hunt by jumping into the air (see video below) so they can shoot themselves through the snow to land on the prey beneath. They locate the rodents they can't see by listening and picking up on the vibrations. But the scientists observing them noticed something. When the fox is facing north (towards the Pole), the fox catches it's prey about three quarters of the time. When it's facing other directions, it's highly unsuccessful.
I've always been curious about what we'll learn about how animals understand the magnetic fields around us that humans seemingly have no awareness of. It is purely instinctual? Are some animals aware of it? Actually use it? Fascinating stuff.
SCIENCE!
