Lots of deer hunters bring a compass when hanging a stand to mark it’s exact relation to the prevailing wind. But that compass can hint at which way a feeding buck will face as he approaches, according to a new study.

From Scientific American:
[German and Czech] researchers have found that when grazing or resting, cattle and deer tend to point their bodies toward Earth’s magnetic poles, which suggests they are able to sense magnetic fields in the same way as many smaller animals.

When the researchers were able to examine the position of the head in the case of. . . deer, they found the animals tended to point north._
