Cattle shown to align north-south

Very interesting! I never noticed this while "tipping cows" If I realised that factor in my oreinteering days I would have forgetten about compass and GPS and grabbed a cow. You learn something new every day. ARGH Cows - they're always up to something sneaky.

Magnetic fields? Next thing is some journalist reporting that cows are the culprits behind crop circles. "The scientists were unable to distinguish between the head and rear of the cattle..." In a related note, the scientists were also unable to distinguish between holes in the ground and their own rear ends. Utter nonsense! Moo!

Thanks to BBC News Goppy, Sik, Doug Parsons, Amielog, Slimey, Mr. Common Sense and Babel fish, the last word can go to St Udio

I've been keeping a mental track of my own sleeping/resting position since the 1970s.
generally myself and all my local relatives favor a north-south alignment.
