Habitat
Fishers primarily inhabit coniferous and mixed forests in North America, preferring areas with dense canopy, fallen logs, and ample tree cover for hunting and denning. They are found in regions from Alaska and Canada south to the Appalachian Mountains and the Pacific Northwest, avoiding open areas and human development.
Diet
Fishers mainly eat small mammals like snowshoe hares, squirrels, and porcupines, which they hunt with agility and persistence. They also consume birds, fruits, and insects, often foraging at dawn and dusk in forested areas.
Behavior
Fishers are solitary animals that are primarily nocturnal, though they may be active during the day in less disturbed areas. They are territorial, marking their ranges with scent and defending them aggressively, and they exhibit curiosity and agility in climbing trees to hunt or escape threats. Fishers are known for their ability to prey on porcupines by flipping them over to attack vulnerable spots.
Conservation Status
The IUCN status of the fisher is Least Concern, with populations stable overall but some regional declines due to habitat loss and historical trapping. Major threats include deforestation and road mortality.
