The red fox is a predatory mammal from the canine family. It has red fur, a pointed muzzle, large ears, and a fluffy tail with a white tip.
The red fox differs from the Arctic fox and corsac fox by its larger body and bright red coloration. It regulates the population of rodents and serves as food for larger predators.

  • The common fox is extremely cautious when in danger and can quickly escape, losing pursuers from sight.
  • The cross fox has large ear flaps that act as sound detectors, capturing vibrations. Ears for the fox are "traps" for prey.
  • In Canada and northeastern Eurasia, cross foxes living along major rivers almost entirely feed on dead salmon fish that died after spawning in winter.
  • The cross fox consumes more than 400 species of animals, not counting several dozen plant species.
  • If the father dies, another bachelor male takes his place, and sometimes the foxes even fight each other for the right to become the stepfather.
  • In winter, the cross fox actively hunts field mice, listening for their squeaks under the snow cover and jumping into the snow to catch prey.
  • Birds are not as important in a fox's diet as rodents, but it can catch a bird if it is on the ground, and also destroys eggs and flightless chicks.
  • Several males often court a female red fox, and violent fights occur between them.
  • A cross fox marked in the Small Tundra was found 600 km southwest and later killed.
  • They are crepuscular.
