The gray fox (Urocyon cinereoargenteus), or grey fox, is an omnivorous mammal of the family Canidae, widespread throughout North America and Central America.This species and its only congener, the diminutive island fox (Urocyon littoralis) of the California Channel Islands, are the only living members of the genus Urocyon, which is considered to be genetically sister to all other living canids.
Urocyon (Greek: "tailed dog" [7]) is a genus of Canidae which includes the gray fox (Urocyon cinereoargenteus) and the island fox (Urocyon littoralis). [2] These two fox species are found in the Western Hemisphere. Whole genome sequencing indicates that Urocyon is the most basal genus of the living canids. [8]
The South American gray fox is a largely solitary animal that has long been hunted for its pelt. The foxes sometimes go near human habitations in search of food, such as chickens and sheep, but tend to avoid areas visited by dogs. They are useful in their role as scavengers of carrion and as dispersers of the seeds of the fruit they eat. [6] [7]
They may also eat eggs and vegetation. Many species are generalist predators, but some (such as the crab-eating fox) have more specialized diets. Most species of fox consume around 1 kg (2.2 lb) of food every day. Foxes cache excess food, burying it for later consumption, usually under leaves, snow, or soil.
The island fox (Urocyon littoralis) is a small fox species that is endemic to six of the eight Channel Islands of California. There are six subspecies, each unique to the island it lives on, reflecting its evolutionary history. They are generally docile, show little fear of humans, and are easily tamed.
However, unlike other desert foxes, it does not have pads covered with hair [7] and cat-like, curved, sharp semi-retractile claws. [ 8 ] The Blanford's fox has an ability to climb rocks and make jumps described as "astonishing", jumping to ledges 3 m (9.8 ft) above them with ease, and as part of their regular movements and climbing vertical ...

The crab-eating fox was originally described as Canis thous by Linnaeus (1766), and first placed in its current genus Cerdocyon by Hamilton-Smith in 1839. [4]Cerdocyonina is a tribe which appeared around 6.0 million years ago (Mya) in North America as Ferrucyon avius becoming extinct by around 1.4–1.3 Mya. living about .
