fabulous fur the fox has got.

They have incredible senses,

particularly their hearing.

Despite having these fairly small ears,

this fox will be able to detect its prey with pinpoint accuracy,

even when it's hidden underneath the snow.

In the depths of the Canadian winter,

a young Arctic fox is searching for food.

He's still a hunting novice.

It's not easy when you can't see your prey.

With his acute senses,

he can hear a faint sound under the snow.

Lemmings.

To catch one,

he uses a special pouncing technique,

known as mousing.

He has to judge its exact distance,

as well as the depth of snow.

To help them find the right spot,

foxes actually align their pounce

to the Earth's magnetic field.

An extraordinary skill.

But mousing isn't always easy,

especially for a beginner.
