The Fisher (Pekania
pennanti) exists as a member of the mustelid family. While frequently
called Fisher Cat, the Fisher is not in any way related to the feline species.
Instead, the Fisher shares many common traits with other mustelids such as; weasels,
martens and otters.
The Fisher’s
native range includes Canada and the northern United States where it thrives in
these regions boreal forests. A crepuscular creature, the
fisher prefers to hunt during dusk and dawn. Despite its common
name, the Fisher rarely eats fish, instead it spends a majority of its time stalking
small mammals, including squirrels, rabbits and its favorite prey the
porcupine. The Fisher exits as one of the few animals able to effective
dispatch and consume porcupines without becoming injured.
Male and female fisher share similar features. Both possess
long, thin, bodies and a sleek black coloration similar to an oversized mink.
Fishers however are much larger than their comparatively diminutive mink
cousins, with male averaging around 10 pounds and females averaging 5 pounds.
The largest Fisher ever recorded weighed 20 pounds. Retractable claws
allow the Fisher with the ability to maneuver well in trees, even possessing
the ability to climb down trees head-first a trait shared by very few mammalian
species.
The Fisher mating cycle starts with both males and females
actively finding mates during March and April. After implantation, the
pregnancy is delayed for 10 months until the following February. Female Fishers then give birth to a litter of
three or four kits in the early spring. The female nurses and cares for the
kits until late summer, when they are 5 months the kits set out on their own to
establish new ranges.
