Why does the fox only jump north?

Winter. Snowy field. Silence. Suddenly the red fox freezes, pricks up its ears, tilts its head, takes aim - and jumps high into the air, head down, straight into the snow! It emerges from under the snow with a mouse in its teeth. What's so strange about it? Here's what you didn't know, but the fox almost always jumps in the same direction - to the north!

In 2011, Czech scientists decided to test a strange thing. They watched 84 foxes, recorded 600 jumps and even the direction of each one — with a compass! And here's what they saw: when a fox jumps to the north or north-northeast, it catches a mouse 73% times. In any other direction — only 18%. Almost 4 times less chance!

How is this possible? After all, a fox can't see a mouse — even under a thick layer of snow! Scientists have come to a fantastic conclusion: a fox senses the Earth's magnetic field. Yes, like a living compass!

Her eyes probably see a shadow or light that only appears when she looks in the right direction. The fox heard the rustle of a mouse, turned north — and by the way the magnetic field and sound "overlap", she accurately calculated the distance to the prey. It's like a game of sea battle, where the fox sees the coordinates!

In addition to the fox, birds (they fly in a swarm), turtles, bees and even dogs can sense the magnetic field. But we, humans, cannot. Imagine how many invisible forces live around us, and animals feel them as we feel the wind. Nature is the greatest inventor in the world.
