FISHER CONTINUED

Range and Habitat: Found in Alaska, Canada and northern United States in mixed wooded areas and in heavily forested areas, preferable coniferous forests.

Habits and Adaptations: Less arboreal than martens; swims well; likes to travel close to water; climbs trees; solitary, except during breeding season; grunts, growls, hisses - vicious fighter; longevity believed to be 8- 10 years. Uses holes or dens dug by other animals as its den; any kind of opening (e.g., hollow trees, rocky ledges). For whelping, the selected nest is an elevated tree cavity. Has been exterminated over most of its range.

Diet: Feeds primarily on small mammals - snowshoe hare, mice, shrews, red squirrels, chipmunks, with porcupines seeming to be a favorite (attacks the head and face, wears it out); fruit and berries, when available; relatively omnivorous.

Breeding and Maturation: May breed at one year; breeding in late March or early April; gestation is about 352 days, including delayed implantation; 1-5 young may be born, usually 2-3; female remates within a week or two after giving birth.

Miscellaneous: Few enemies other than man; fur is valuable to trappers; is believed never to have been very densely distributed.
