* Weasels: You'll find both Long-tailed Weasels and Short-tailed Weasels (also called "least weasels") in middle Tennessee. These are common throughout the state.
* Martens: The Pine Marten is a shy, elusive species found in the higher elevation forests of the Cumberland Plateau in middle Tennessee.
* Ferrets: The Black-footed Ferret is the only native ferret species in North America and is critically endangered. Their historical range did not include middle Tennessee. They are only found in the wild in a few areas of the Great Plains, with reintroduction efforts in other states.
Therefore, you are likely to encounter wild weasels or martens in middle Tennessee, but you will not find wild ferrets.
