[Rockhounds] Cows point north thanks to magnetite crystals

[Kreigh Tomaszewski]

Yes, it has recently been found that cows sense the Earth's magnetic  
field and prefer to orient facing north. Here is another link to the  
story

BTW, if you are going into the wilderness, you might want to take along  
a compass you can eat if things get desperate.	;-}

OT: Do cows in the southern hemisphere face south?

Cows also seem to be sensitive to ground currents. Milk production  
drops off, and the cows tend to get sick. Current changes and  
transients also produce behavior changes.

One of the known precursors of earthquakes is ground currents.

It makes me wonder if we could beef up our ability to sense earthquake  
precursors by turning dairy farms into detector farms?

Can anyone report on what a herd heard before a local earthquake?
