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.
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?
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.
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.
oh yeh, and energy.... The person who says it cannot be done should not interrupt the person doing it. Chinese Proverb.
I don't like staring into the sun, personally. Do cows?
Only when they wear sunglasses. "Ne te courbe que pour aimer..." René Char

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