_Description._--Because of the value and lasting popularity of its fur, the mink is known to all. Few persons, however, recognize the animal in the wild. The mink possesses the long, slim body and short, rather stout legs of a weasel but has a more bushy tail. The mink is larger than the weasel. Large males weigh up to 3 pounds; females 1-1/2 pounds. Males measure about 2 feet in length, of which the tail comprises eight inches. Females measure about 20 inches and have tails 7 inches long. The color is rich, dark reddish or chocolate brown. The underparts are slightly paler than the back. There are usually small white markings on the chin, chest or other part of the ventral surface. These markings sometimes take the form of narrow white lines. The mink ranges from the Atlantic to the Pacific and from Alaska south to Florida, New Mexico and central California. It is active throughout the year and is principally, though not exclusively, nocturnal. McMurry (1940: 47) records three mink seen at 3:30 p. m. on August 8, 1939, at Packwood Lake, Lewis County, one of which was carrying a garter snake two feet in length. This mustelid is semiaquatic, living along rivers, streams, lakes and salt water and spends most of its time along the shore, on muddy or sandy beaches. In this respect it resembles the raccoon. Whereas the raccoon spends a part of its time on the land, the mink spends a corresponding amount of its time in the water. It is an excellent swimmer, able to overtake and capture fish in the water. In the San Juan Islands minks have forsaken the shoreline and roam over the uplands, feeding on the abundant, feral domestic rabbits. I found evidence of their presence far inland, miles from water, in grassy and bushy wastes; along the beaches their tracks were rarely seen. Along Puget Sound, minks spend part of their time on the beaches, feeding on dead fish and other marine animal life. These animals, however, seem to live along the rivers and streams flowing into the sound. Along the ocean coast, some minks seem to live exclusively in the marine shoreline habitat. The mink ascends some distance into the Cascade and Olympic mountains along the larger watercourses. There are reliable reports of minks from Heart Lake and Lake Dorothy, King County, high in the Cascades. These animals were seen in the summer but they may live in higher parts of the Cascades, at least about some of the larger lakes throughout the year. As far as is known there are no minks on the Columbian Plateau.
