Red foxes are the most widely distributed wild carnivores in the world, occurring in North America, Asia, Europe, and North Africa. They are also widespread in Australia, where they were introduced in about 1850 so that fox-hunters would have something to hunt. Their range in North America has expanded since colonial times as their competitors, wolves, were eliminated, but their range has also contracted in areas where they are in competition with coyotes. Red foxes prey on voles, rabbits, hares, and other small mammals, and also eat birds, fruits, and invertebrates even beetles and earthworms. A male female pair typically inhabits a territory, and older, usually female, siblings help care for the younger offspring by bringing them food. Red foxes are among the main carriers and victims of rabies.
