The fisher (or pékan) is a forest-dwelling mustelid native to North America. Unfortunately, the fisher is another one of those mustelids whose name is often misspoken as a compound of another species. You’ll often hear them called ‘fisher cats’, when they have no relation to felines. They have a lifespan of about 10 years.
The fisher was previously placed with the martens in genus Martes, until DNA analyses suggested a number of differences and evolutionary relations, and it was given its own genus, Pekania. The fisher is a tactician that knows how to handle porcupines, and is more brutish in its ways as well as bulkier and larger than the true martens of genus Martes.
Its name is misleading, given that the animal seldom hunts fish. However, it’s possible that ”fisher” is derived from the French word ”fichet”, which means ”ferret”. The fisher mainly feeds on small mammals, birds, insects, nuts, berries and carrion.
