Tracks can be found where the water meets the shore. Mink live near creeks, rivers, streams, ponds, and lakes. Mink tracks show five toes on both front and hind feet. The front track often shows only four toes. Tracks are a bit more than an inch long. The toes of mink tracks can appear pointed due to the claw marks. The five toes are asymmetrical in arrangement, with the inner toe (the smallest one) being set back further in the track. This is very visible on the hind tracks.

The Mink

Mink are mustelids and relatives of the weasel. Mink are bigger than weasels and are aquatic. Minks are usually nocturnal, but are sometimes active around dawn and dusk. These animals usually hunt alone. They do not hibernate in the winter. They continue to hunt, sometimes even traveling under ice that has formed on the river surface.

Minks will eat poultry as well as their eggs. They will kill them by biting them through the skull or neck, but sometimes will attack the vent. Closely spaced pairs of canine tooth marks are a sign of a mink or weasel. Sometimes multiple birds are killed, and may place them neatly in a pile. To consume the eggs, they will completely crush the shells similar to what a weasel and opossum does.

How to Prevent Mink Attacks

Eliminate entry points : Close all openings larger than 1 in (2.5 cm). Use a 1//2 in (1.3 cm) hardware cloth, similar wire mesh, or other materials to block openings.
