While their cuteness may be disarming, don't let that fool you into thinking red foxes are anything less than cunning and resourceful. According to an article in Discover Magazine, a scientific investigation into their hunting techniques led to a major conclusion: They use magnetic fields to line up their attack. In order to achieve an astounding kill rate of over 70%, they seem to base their approach on a combination of their prey's noises with the slope of the Earth's magnetic polarity. It's been described as their "rangefinder." Their success rate dropped dramatically when not taking this approach. Good thing the foxes use it frequently, since who knows what sort of tricks they'd could develop if left hungry.
