While the red fox, which is the most common species, has a distinctive white tip on its tail, other fox species have different tail colors:
* Arctic fox: has a white tail in winter and a blue-grey tail in summer.
* Gray fox: has a black-tipped tail, not white.
* Kit fox: has a black-tipped tail.
* Fennec fox: has a fluffy, white tail.
* Corsac fox: has a black-tipped tail.
So, the color of a fox's tail can vary depending on the species and even the season.
