Well thank goodness there was a study done on this! According to some scientists, there is a belief that cattle and other herd animals might have the ability to track north and south by magnetics. They are being compared to those animals that migrate--birds, butterflies and even sea turtles.
This study, like many others, has me shaking my head. Number one, what am I supposed to do with this information, except maybe win a round of Trivial Pursuit?
Number two, aren't there more pressing studies to be done? Cancer, hunger, world peace, number of licks it takes to get to the center of a Tootsie Pop? Wait, that one's been done.
Number three, did these scientists bother to test which way the wind was blowing? In my experience, herd animals tend to turn their backsides to the prevailing wind. My experience also tells me that, in general, the wind tends to blow out of the north and south. Seldom do we get a wind out of the east or west.
Oh well, if I'm ever lost in the middle of a pasture, I'll be sure to seek out cattle to point the way home.
