I just read in a magazine how the majority of cows align their bodies in the north-south direction. So the minority of cows face east or west when resting or grazing. I haven't been by any farms to do my own research, but this is definitely something to look for the next time you're driving past a farm. This behavior is thought to be related to the Earth's magnetic field and has been found to occur in other species as well.
