The kit fox (Vulpes macrotis) is a fox species that inhabits arid and semi-arid regions of the southwestern United States and northern and central Mexico. These foxes are the smallest of the four species of Vulpes occurring in North America and are among the smallest of the vulpines worldwide. It has also been called a North American counterpart of the fennec fox due to its large ears.
It has been suggested that this fox is the same species as the Swift fox – though genetic analysis suggests that this is not the case. It has also suggested that, due to its ears, this is essentially the American Fennec fox
The endangered San Joaquin kit fox is a recognized subspecies. It is found in around 8 states in the USA. Its population has been depressed, in parts of its range – as a result of the extinction of the wolf in California. As a result of this local extinction, there is far less predation on the coyote, which has lead to the coyote eating more of these kit foxes.
