I took this picture of a Grey Fox in a tree some time ago with my first digital camera, Nikon D100 while visiting Mena Arkansas. It was an awesome sight, but the picture came out with too much noise, hence better viewed small.

GENERAL INFORMATION
The Gray Fox is a mammal of the order Carnivora ranging throughout most of the southern half of North America from southern Canada to northern Venezuela and Colombia.This species and the closely related Island Fox are the only living members of the genus Urocyon, which is considered to be among the most primitive of the living canids.

The Gray Fox is distinguished from most other canids by its grizzled upper parts, strong neck and black-tipped tail, while the skull can be distinguished from all other North American canids by its widely separated temporal ridges that form a U-shape. There is little sexual dimorphism, save for the males being slightly but smaller than females. The Gray Fox ranges from 800 to 1125 mm (31.5 to 41.3 inches) in length. Its tail measures 275 to 443 mm (10.8 to 17.5 inches) and its hind feet measure 100 to 150 mm (4.9 to 5.9 inches). It weighs 3.6 to 6.82 kg (7.9 to 15 lbs).³ It is readily differentiated from the Red Fox by the lack of “black stockings” that stand out on the latter.

The Gray Fox’s ability to climb trees is shared only with the Asian Raccoon Dog among canids. Its strong, hooked claws allow it to scramble up trees to escape predators such as the Domestic Dog or the Coyote, or to reach tree-bound or arboreal food sources. It descends primarily by jumping from branch to branch, or by descending slowly backwards as a House Cat. The Gray Fox is nocturnal or crepuscular and dens in hollow trees, stumps or appropriated burrows during the day.
