HOW DO RED FOX SURVIVE WINTER?

Good morning Little Red!

This young Red Fox was spotted early one recent morning, hungrily scraping the ground for food. Perhaps he was hunting a small rodent or digging for grubs. How have the Red Foxes that were born in our neighborhoods last spring adapted to survive winter’s harsh temperature and snowy scapes?

Red Fox have evolved with a number of strategies and physiological adaptations. Their fur coats grow  thick and long, up to their footpads, which aid in heat insulation. Adult Fox begin to moult, or shed, their winter coat typically in April. Young Red Fox do not moult at all the first year but continue to grow fur until their second spring.

Red Fox tails are extra thick and when not cozily curled up in a snow bank, they will lay on the ground with their tail wrapped around for extra warmth.

Red Fox have relatively small body parts including their legs, ears, and neck, which means less body surface is exposed to frigid temperatures allowing them to conserve body heat. During the winter, Red Fox are less active than during the summer months. Decreased activity also helps to conserve body heat.

The Red Fox’s diet varies according to seasonal abundance. In the summer their diet is supplemented with berries, apples, pears, cherries, grapes, grasses, and acorns. All year round they feed on grubs and insects as well as small mammals such as rabbits, rodents, and squirrels. Red Fox have extraordinarily sharp hearing largely because their ears face outward. They can detect a mouse a football field away, under cover of  snow!
