Typical den sites include rock formations, hollow logs or trees, burrows, and brush piles. Dens are often lined with grass, leaves, or shredded bark. The gray fox is most active at night, but can sometimes be seen in the daytime. Gray foxes have been found in squirrel nests and abandoned hawk nests up to 60 feet above the ground. This habit is useful for escaping enemies, sunbathing, and eating fruits or other foods found in trees.
Gray foxes are secretive and shy, but can fight fiercely when necessary.
They can run about 26 miles per hour for short distances. Foods Rabbits and rodents make up the bulk of their diet. Corn, berries and fruits like persimmons can be important foods at certain times of the year. Reproduction The gray fox breeding season extends from January to mid-May, but peaks in February or the first week of March. One litter per year is born between March and mid-May.
