The red fox originated from smaller-sized ancestors from Eurasia during the Middle Villafranchian period, and colonised North America shortly after the Wisconsian glaciation. Among the true foxes, the red fox represents a more progressive form in the direction of carnivory. Apart from its large size, the red fox is distinguished from other fox species by its ability to adapt quickly to new environments and, unlike most of its cousins, is not listed as Endangered anywhere. Despite its name, the species often produces individuals with abnormal colourings, including albinos and melanists. Forty-five subspecies are currently recognised which are divided into two categories: the large northern foxes, and the small, primitive southern foxes of Asia and the Middle East.
Red foxes are social animals, whose groups are led by a mated pair which monopolises breeding. Subordinates within a group are typically the young of the mated pair, who remain with their parents to assist in caring for new kits.The species primarily feeds on small rodents, though it may also target leporids, game birds, reptiles, invertebrates and young ungulates. Fruit and vegetable matter is also eaten on occasion. Although the red fox tends to displace or even kill its smaller cousins, it is nonetheless vulnerable to attack from larger predators such as wolves, coyotes, golden jackals and medium and large felines.
The species has a long history of association with humans, having been extensively hunted as a pest and furbearer for centuries, as well as being prominently represented in human folklore and mythology. Because of its widespread distribution and large population, the red fox is one of the most important furbearing animals harvested for the fur trade.
