Spiegel Online: Cows Demonstrate Mysterious Inner Compass

Red deer and cows orient themselves on a North-South axis, showing a previously undocumented feel for points of the compass. German scientists discovered the strange alignment by analyzing Google Earth images of 308 pastures.

Do cows have a sixth sense? Herd animals seem to arrange themselves according to a certain logic. On cold sunny days, many cows stand so that the warming sun rays will hit them directly. On cold, windy days, they orient themselves parallel to the wind exposing a smaller portion of their body to it.

So far so good. But where do cows choose to stand on warm days without significant wind? A team of German and Czech scientists from the University of Duisberg-Essen believe they have discovered a pattern in the animals' natural positioning: grazing and resting animals arrange their bodies along a north-south axis. Researchers published this first evidence of bovine sensitivity to the Earth's magnetic fields Monday in scientific journal PNAS (Proceedings of the National Academy of Sciences USA).

I thought up a way to test this idea. The magnetic field in the northern hemisphere pulls down the north end of a compass more than the south end, so you need to get your compass rebalanced if you take it to the southern hemisphere.

Therefore, if you take European cattle to the southern hemisphere, their internal compasses might not work as well. New Zealand is the place to test this idea.

Or you could look out of my window. I have never seen the cows in the field at the end of my garden aligning themselves north/south. They're usually in a random jumble of alignments.

And - here's a thing - they move around.

Isn't it slightly suspect to use a small number of Google Earth images as data points, instead of testing the hypothesis with real animals?

You know, I was thinking the Sun is on average much closer to the South direction that to the East or West direction when cattle are on a field... maybe that has an influence on cattle orientation?

Well, if they enjoy having their arses warmed, possibly.

I think I'll need to be more convinced that there's data to be explained first. You can't tell the weather or ambient temperature from Google Maps with any reliability, so it all sounds a little unlikely.

Um, I don't like staring into the sun, personally. Do cows?

Cows usually stare at the grass. Occasionally they look at each other and moo.

It's hard work for a cow to raise its head to the 40-50 degrees above the horizon needed to look straight into the sun, and even harder work to hold that position. (Assuming there's sun to be seen, which in the UK, there usually isn't.)

And now, I will leave the commas in peace and get on with some work.

lol, where else but ET, serious discussion of cows' geomanticity juxtaposed with police state rumblings, presidential gymkhanas, and cold war realpolitik?

oh yeh, and energy....

Only when they wear sunglasses.

Don't they know that's bad for their eyes?

It looks like they haven't been told...

That's not a UK cow. There's blue sky, so it can't be a UK cow.

Maybe German cows have a better sense of direction? (And style.)

Google Maps? Are you sure you don't mean Google Earth? I already have mental images of driving directions such as "Turn left after the third cow".
