Common mink
Around two feet in length, mink weigh only 2-3.5 pounds (Virginia DWR).While on the hunt, these lithe predators patrol the banks of the Shenandoah or dive below its surface. During many years of observations, I’ve yet to see more than one mink at a time.
Mink are predators of muskrats (Virginia DWR). Once, while watching a muskrat family out foraging and grooming next to a beaver lodge, I saw a mink stealthily wend its way through the logs. Every so often, the muskrats would catch sight of it and dive underwater, but then would quickly return.
