CHICAGO (Reuters) - Grazing cattle and sleeping deer tend to align their bodies along the North-South axis of the Earth's magnetic field, European researchers said on Monday, giving new meaning to the phrase animal magnetism. Herdsmen and hunters have long known that cattle and sheep tend to face the same direction when grazing, but had believed they were simply positioning themselves according to prevailing winds or the sun's rays. Sabine Begall of the University of Duisburg-Essen in Germany and colleagues had a different idea. The researchers studied 8,510 satellite images of cattle and deer herds derived from Google Earth from around the globe, including 308 pastures and plains. They also looked at deer beds -- impressions left in the snow by resting deer -- from nearly 3,000 deer in more than 225 locations in the Czech Republic.
