The sensitivity of cows

Have you ever noticed how most cows align themselves in a north-south direction? Actually, neither have I. But if you ever do, you'll know it's not just a happenstance. Apparently, there is now proof that cows and deer (at least) are sensitive to magnetic fields. When they are near overhead electrical wires running east-west, they tend to line up the same way. The reason they line up north-south in the absence of electrical wires is because of the earth's own magnetic field.

Notice how most of these cattle are lined up in the same direction...
