This Gray Fox is in the Hassayampa River Preserve of the Nature Conservancy near Wickenburg, Arizona. Although primarily nocturnal, the Gray Fox may sometimes be seen foraging during the day as in this image, seeking primarily small mammals.

The Gray Fox is the only member of the dog family that can climb trees, usually to seek refuge or in search of roosting birds. It can reach a speed of 28 mph for short distances and has lived for up to 10 years in captivity; longevity in the wild is probably much shorter.
