What is a "fisher"?

The fisher, also known as "Martes pennanti," is a medium-sized mammal belonging to the mustelid family. It is native to North America and is known for its sleek, dark brown fur and long, bushy tail. Fishers have a stocky build with short legs and a broad head. They are skilled climbers and are known for their ability to navigate through dense forests. Fishers are primarily carnivorous, with a diet that includes small mammals, birds, insects, and fruits. They are known for their excellent hunting and trapping skills, and are considered to be efficient predators. Fishers have a solitary and elusive nature, and are mainly active during twilight and nighttime hours. They are important members of their ecosystems, playing a role in controlling populations of small mammals. Conservation efforts are in place to protect fisher populations, as they have faced habitat loss and trapping pressures in some areas.
