BBC NEWS | Science/Nature | Cattle shown to align north-south

Wild deer also display this behaviour - a phenomenon that has apparently gone unnoticed by herdsmen and hunters for thousands of years.
In the Proceedings for the National Academy of Sciences, scientists say the Earth's magnetic fields may influence the behaviour of these animals.

Many species - including birds and salmon - are known to use the Earth's magnetic fields in migration, rather like a natural GPS. "
