The grey fox can be identified by its strong neck, black-tipped tail and unique U-shaped skull. It easily climbs trees and enjoys hunting alone in wooded, amply brushed areas of North America, Canada and parts of Venezuela and Colombia.

As an omnivorous, solitary hunter, the grey fox will eat a variety of voles, shrews, birds, rodents and rabbits while also enjoying fruits, corn, apples, nuts and berries.

The grey fox mating season ranges from January to April, and females gestate for 53 days, giving birth to a litter of about seven pups. Males help in the rearing and feeding of the pups, which are weaned at about three months old and venture off to hunt on their own a month later. They are also monogamous animals, usually mating with the same partner every year.

This species and the related island fox are the only living members of the genus Urocyon, a biological family of mammals that are both carnivorous and omnivorous.

Lives in areas from southern Canada to parts of northern Colombia and Venezuela.
