This beautiful and graceful member of the weasel family is chiefly seen after nightfall, but is also occasionally encountered along the trails during the day. At Paradise Valley a pair lived in the old Community House for several years, and were the source of a keen thrill to the visitors who saw them playing around the building. For the most part the marten is a resident of the dense forest. It is an expert climber, travels through the trees almost as well as a squirrel, and is equally at home among the talus slopes where it searches for conies. The marten eats a wide variety of foods, with small game such as mice most commonly taken. Chipmunks, wood rats, squirrels, rabbits, pikas, birds and occasionally insects and berries are other important food items. Young martens are usually born from April to June and normally number around four to six in a family. The home is located in hollow trees or logs, or among the rocks. FISHER _Martes pennanti_ (Erxleben) The fisher is considerably larger than the marten, although resembling this near relative in general characteristics. The coloration above ranges from buffy gray to brownish black, with the under parts black or blackish. The hair over the head, neck and shoulders has a grayish appearance. Spots of white may occur on the throat and breast. _Specimens in park collection:_ None. The fishers are now confined almost entirely to the northeastern United States and Canada, west to British Columbia, although rather common in the Sequoia-Kings Canyon National Park. Its occurrence within the park is open to question as no records have been obtained for several years. Investigation in the more remote sectors may disclose its presence. It was once known to range from the park boundaries to forest line. The name “fisher” is somewhat of a misnomer, as the animal is not known to catch fish or even to live close to streams. It will eat fish if the opportunity arises, however. It has a wide variety of common names, including that of pennant marten, pekan, and black cat. Like the marten, the fisher is a lover of the deep woods and is reportedly very agile in the trees. It feeds principally upon rabbits, squirrels, mice, small birds, and frogs. It is not adverse to killing and eating the marten. One of its most interesting sources of food is the porcupine, which the fisher manages to kill without serious injury from the sharp quills. A litter of from two to four young, which are born in a nest in a hollow log or tree, are raised annually. MINK _Mustela vison energumenos_ (Bangs) The body of the mink is somewhat like that of a weasel, but heavier and considerably larger. The legs and ears are short; the tail is bushy. The coloration is brown, darkening along the back and becoming almost black on the tail. Sometimes irregular white streaks or spots occur on the throat, chest or belly.
