Gray fox are also sometimes known as the “tree fox” or the “cat fox”. Their pupils are oval shaped, rather than slit-like. These fox are common, but very elusive and rare to spot in the wild. They are primarily nocturnal, but may forage during the day. Spotting them on the trail cam is a real treat!

Their 6 inch-long ears help regulate their body temperatures. You can visit our fennec foxes, Charlie and Daisy, at the Small Mammal House! #WeSaveSpecies | Smithsonian’s National Zoo and Conservation Biology Institute | Facebook
