With its body curled tight and its tail pulled in, the red fox can minimize heat loss and stay warm even in very cold temperatures. Red foxes hunt rodents throughout the winter by listening for them under the snow. The foxes can often be seen comically tilting their heads from side to side, trying to pinpoint exactly where their prey is below the snow. When they think they’ve got it right, they leap in the air and then bust through the snow to catch the unsuspecting rodent. // A good night's sleep is going extinct.
