The Swift Fox (Vulpes velox) is a small fox found in the western grasslands of North America, such as Colorado, New Mexico and Texas. They also live in Manitoba, Saskatchewan and Alberta in Canada.

Taxonomy

The swift fox is closely related genetically to the kit fox Vulpes macrotis, but occupies a different geographical range. The two have historically been regarded as different species, for reasons basically related to size: the kit fox is slightly smaller than the swift fox, and the former has a narrower snout. However, hybrids between the two occur naturally where their ranges overlap, and some mammalogists (e.g. Dragoo et al, 1990) classify the two as subspecies of a single species, usually treated as Vulpes velox (with the swift fox being described as V. velox velox and the kit fox as V. velox macrotis). The molecular genetics evidence is not conclusive however, and some of those who have used it (e.g. Mercure et al, 1993) continue to treat the swift fox and kit fox as separate species. This article is not written in the formal tone expected of an encyclopedia article. ... Molecular genetics is the field of biology which studies the structure and function of genes at a molecular level. ...


Conservation status

The species was extirpated from Canada by 1938, but a reintroduction program started in 1983 has been successful (Sillero-Zubiri & Hoffmann, 2004). However, in May 2000, the Canadian Species at Risk Act listed the swift fox as an endangered species in Canada[1]. In general, though, the IUCN Red List characterises it as of Least Concern, because populations elsewhere in its range are stable or increasing. The IUCN Red List of Threatened Species (also known as the IUCN Red List and Red Data List), created in 1963, is the worlds most comprehensive inventory of the global conservation status of plant and animal species and can be found here. ...


General characteristics

Swift foxes weigh 2 or 3 kg (4 to 7 pounds). The average size is 2.8 feet long, with a tail ranging in length between nine and thirteen inches. They are primarily nocturnal, and are more heavily dependent on their dens than most North American canids. They suffer serious predation by coyotes. A nocturnal animal is one that sleeps during the day and is active at night - the opposite of the human (diurnal) schedule. ... Look up lair in Wiktionary, the free dictionary. ... Genera Alopex Atelocynus Canis Cerdocyon Chrysocyon Cuon Dusicyon Fennecus Lycalopex Lycaon Nyctereutes Otocyon Pseudalopex Speothos Urocyon Vulpes Canidae is the family of carnivorous and omnivorous mammals commonly known as canines. ... For other uses, see Coyote (disambiguation). ...


Like most canids, the swift fox is an omnivore. Rabbits, mice, ground squirrels, birds, insects and lizards are staples. Grasses and fruits round out their diet. However, like any efficient forager, the swift fox takes advantage of seasonal foods. During the summer, adults eat large amounts of insects, including beetles and grasshoppers and feed their young with larger prey items. Winter-killed deer and other carrion may also be important food sources. Pigs are omnivores. ... For other uses, see Rabbit (disambiguation). ... This article is about the animal. ...

Adult swift foxes live in pairs and may mate for life. They may occupy up to thirteen dens in one year, moving because prey is scarce or because skin parasites build up inside the den. Sometimes they make other burrows from other animals bigger, even though they are completely capable of digging one on their own. Recent research has shown that social organization in the swift fox is unusual among canids, since it is based on the females. Females maintain territories at all times, but males emigrate if the resident female is killed or removed. A parasite is an organism that spends a significant portion of its life in or on the living tissue of a host organism and which causes harm to the host without immediately killing it. ... In ethology, sociobiology and behavioral ecology, the term territory refers to any geographical area that an animal of a particular species consistently defends against conspecifics (and, occasionally, animals of other species). ...

Hinterland Who's Who - Swift Fox (2229 words)
In winter, the swift fox’s fur is long and dense, mainly buff-grey on the head, back, and upper surface of the tail, and orange-tan on the sides, legs, and lower tail surface.
However, despite the serious overall decline of the swift fox population in the United States and the eradication of the species in some states, the foxes managed to hold out in the central United States, where habitat change and trapping and poisoning campaigns were no less threatening than in Canada.
Although the majority of the original stock of released foxes has perished, scientists are encouraged by the survival of a nucleus of second-generation foxes born and raised completely in the wild, and monitoring and releases will continue until several generations of foxes have been born.
Swift Fox (698 words)
Historically, the swift fox was widely distributed from southern Canada to the panhandle of Texas, and from northwest Montana to western Minnesota.
Swift fox are apparently absent from North Dakota, although several recent observations suggest the species may exist in extremely low densities in the southwestern counties.
Swift fox were historically trapped for their fur, but their pelts are of low quality and small in size.
