Habitat: Fishers can be found in forested areas of North America.

Diet: Fishers mainly feed on small mammals, birds, insects, nuts, berries and carrion.

Breeding: Fishers breed in late March or early April and implantation is delayed for 10 months until January or February the following year. After a gestation period of approximately 50 days, females will give birth to 1 - 6 kits then 7 - 10 days later they enter estrus and the breeding cycle begins again.

At birth the kits are blind and helpless, but after 3 weeks they begin to crawl around in the nest. At 7 weeks they open their eyes and at 8 weeks they begin to climb. They are weaned at 8 - 10 weeks and when they reach 4 months old they begin to become intolerant of one another.

After 5 months their mother pushes them out on their own and by the time they are a year old the youngsters have established their own ranges.

Predators: Humans are predators of Fishers.
