The red fox is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, being present across the entire Northern Hemisphere from the Arctic Circle to North Africa, North America and Eurasia. Its range has increased alongside human expansion, having been introduced to Australia, where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included among the list of the "world's 100 worst invasive species". The red fox can be found in most of the United States and Canada, except for the far north in Canada and Alaska and much of the western U.S. and Hawaii. The red fox is found throughout New Hampshire. The red fox is also found in Europe and Asia and it has been introduced to Australia.
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. Despite its name, the species often produces individuals with other colourings, including albinos and melanists.

Red foxes are usually together in pairs or small groups consisting of families, such as a mated pair and their young, or a male with several females having kinship ties. The young of the mated pair remain with their parents to assist in caring for new kits. The species primarily feeds on small rodents, though it may also target rabbits, game birds, reptiles, invertebrates and young ungulates. Fruit and vegetable matter is also eaten sometimes. Although the red fox tends to kill smaller predators, including other fox species, it is vulnerable to attack from larger predators, such as wolves, coyotes, golden jackals and medium- and large-sized felines.
The word "fox" comes from Old English, which derived from Proto-Germanic *fuhsaz. Compare with West Frisian foks, Dutch vos, and German Fuchs. This, in turn, derives from Proto-Indo-European *puḱ- 'thick-haired; tail'. Compare to the Hindi pū̃ch 'tail', Tocharian B päkā 'tail; chowrie', and Lithuanian paustìs 'fur'. The bushy tail also forms the basis for the fox's Welsh name, llwynog, literally 'bushy', from llwyn 'bush'. Likewise, Portuguese: raposa from rabo 'tail', Lithuanian uodẽgis from uodegà 'tail', and Ojibwa waagosh from waa, which refers to the up and down "bounce" or flickering of an animal or its tail.

The red fox has an elongated body and relatively short limbs. The tail, which is longer than half the body length, is fluffy and reaches the ground when in a standing position. Their pupils are oval and vertically oriented. Nictitating membranes are present, but move only when the eyes are closed. The forepaws have five digits, while the hind feet have only four and lack dewclaws. They are very agile, being capable of jumping over 2-metre-high (6 ft 7 in) fences, and swim well. Vixens normally have four pairs of teats, though vixens with seven, nine, or ten teats are not uncommon. The testes of males are smaller than those of Arctic foxes. Their skulls are fairly narrow and elongated, with small braincases. Their canine teeth are relatively long. Sexual dimorphism of the skull is more pronounced than in corsac foxes, with female red foxes tending to have smaller skulls than males, with wider nasal regions and hard palates, as well as having larger canines. Their skulls are distinguished from those of dogs by their narrower muzzles, less crowded premolars, more slender canine teeth, and concave rather than convex profiles.

Except for breeding females, the fox doesn't usually use a den. Sometimes it will sleep in the open, wrapping its bushy tail around its nose to stay warm. When it does use a den, it will usually find an abandoned rabbit or marmot den instead of making its own den. Red foxes either establish stable home ranges within particular areas or are itinerant with no fixed abode. They use their urine to mark their territories. Red foxes live in family groups sharing a joint territory. In favourable habitats and/or areas with low hunting pressure, subordinate foxes may be present in a range. Subordinate foxes may number one or two, sometimes up to eight in one territory. These subordinates could be formerly dominant animals, but are mostly young from the previous year, who act as helpers in rearing the breeding vixen's kits. Alternatively, their presence has been explained as being in response to temporary surpluses of food unrelated to assisting reproductive success. Non-breeding vixens will guard, play, groom, provision and retrieve kits, an example of kin selection. Red foxes may leave their families once they reach adulthood if the chances of winning a territory of their own are high. If not, they will stay with their parents, at the cost of postponing their own reproduction.
The red fox is mostly nocturnal, although it will sometimes venture out in the day. The red fox, unlike other mammals, hears low-frequency sounds very well. It can hear small animals digging underground and will frequently dig in the dirt or snow to catch prey. The fox stalks its prey, much like a cat. It gets as close as it can and then pounces and chases its prey.

Life Cycle

The red fox mates from January through March. The female will make one or more dens right after mating. A little less than two months after mating, the female gives birth to a litter of between one and ten kits. The male brings the female food while she is caring for the kits.
The kits start playing outside the den when they are about a month old. The mother begins feeding her kits regurgitated food, but eventually she will bring them live prey to "play" with and eat. Playing with live prey helps the young kits develop the skills they will need for hunting. The kits leave their mother when they are about seven months old.
