Cows automatically point to the north because they have their own in-built compasses aligning them with the Earth's magnetic field, scientists have discovered.
Dr Sabine Begall and colleagues from the University of Duisburg-Essen have discovered that cows tend to point north.
The researchers studied deer in the Czech Republic and looked at thousands of images of cattle on Google Earth. The animals tended to face north when eating or resting.
"We conclude that the magnetic field is the only common and most likely factor responsible for the observed alignment," the scientists wrote in an article.
