Their fur tends to be darker in the winter, and becomes lighter during the summer. Known for the high-pitched shriek that sounds like a woman screaming, many believe that this noise is mistaken for a fox.
Those who back the claim that fisher cats do indeed make these screams, say the fishers use this as a mating call, as well as a predatory warning.
Fishers prefer forest regions, both coniferous and deciduous. These environments provide them with the ability to climb from tree to tree in search of food, as well as provide them shelter.
Often, they will take up residence in hollowed out trees like spruces, firs, and white cedars. This is because their favored prey are usually found in these same habitats. Despite being able to climb trees, fishers spend most of their time on the forest floor, and prefer thick forests to other habitats. Found in both softwood and hardwood forests, fishers frequent areas of forests with overhead cover, and tend to avoid those areas without cover.
Fishers enjoy a forest floor with fallen trees and woody debris. Heavily logged areas are typically avoided by female fishers, since they need large trees for denning.
Secretive and elusive creatures, fisher cats keep their distance from humans and typically do not den under buildings.
However, with fisher sightings steadily increasing since , concerns among homeowners are becoming more common. There are several contributing factors that could be the reason for the increase in sightings:. Increased flexibility of habitat previously assumed to only survive in larger, contiguous forest.

They once ranged throughout the forests of Canada and the northern U. You might see fisher cats scampering up the trunks of trees or zipping along across the the ground.
Hollow trees, stumps, holes in the ground, brush piles, and other organic matter may be temporary housing for these creatures as they are out looking for food during the day and at night. Fishers are not dangerous to humans. In New England, for example, biologists have found that fisher cats seem to enjoy dining on gray squirrels Sciurus carolinensis most often, Northern Woodlands magazine reported.
The animals also eat fruit, reptiles and amphibians, birds and bird eggs, other small mammals, and even each other, according to a study published in the journal BioOne Complete. The study's authors examined the stomach contents of 91 fishers, whose carcasses they had found in Pennsylvania.
Of these fishers, 12 had bits of other fishers in their digestive tracts. The team speculated that the Pennsylvania population of fishers had grown so large so quickly that the animals were competing with each other for food and had grown aggressive toward one another.

As the porcupine tires out, the fisher will snap at the quilled animal's face. Enough bites to the face, and the porcupine will eventually bleed out and die. Once the prey has died, the fisher will grasp the porcupine's face in its jaws and twist the prickly creature upside down to expose the belly, so the fisher can safely eat without getting quilled.
However, fishers are sloppy eaters and will occasionally swallow a quill or two, Joyce said.
