The gray fox (Urocyon cinereoargenteus) is a carnivoran mammal of the family Canidae ranging throughout most of the southern half of North America from southern Canada to the northern part of South America (Venezuela and Colombia).This species and the closely related Channel Island fox (Urocyon littoralis) are the only living members of the genus Urocyon, which is considered to be among the most primitive of the living canids.
