Deer Grazing

Jay at "Scenic Videos" says, " Cattle and deer all over the world tend to align themselves with Earth's magnetic field, according to new research.

Both types of animals appear to graze in a north-south direction that aligns with magnetic north, not geographic north, according to European researchers who scrutinized thousands of Google Earth images.

Birds, turtles, and fish are known to use magnetic guidance in migration. And among small mammals, a handful of rodent and one bat species have been shown to possess a magnetic compass.

Sabine Begall, a zoologist at the University of Duisburg in Essen, Germany, and her colleagues propose that large mammals may also sense Earth's magnetic field.

But why the non-migrating animals would align themselves according to Earth's magnetism is still a mystery."
