Pekania pennant • Mammals
The fisher has fur that varies seasonally, being denser and glossier in the winter. During the summer, the color will become more mottled, as the fur goes through a molting cycle. Fishers have 5 toes on each foot with unsheathed retractable claws that let them scale trees like a cat. They can also rotate their feet 180 degrees, allowing them to come back down headfirst. Their feet are large, giving them good traction and making it easier to move on top of snow
The fisher feeds on a wide variety of small animals and occasionally on fruits and mushrooms. It shows a preference for the snowshoe hare and is one of the few predators able to prey on porcupines successfully. Despite its common name, the fisher seldom eats fish, and instead, prefers to hunt in full forest, foraging around fallen trees.
Fishers live in the Sierra Nevadas, in addition to Yosemite National Park and on California’s northern boundary. Females den in hollow trees and kits are born blind and helpless. At 5 months of age, their mother pushes them out on their own. At 1 year old they live on their own.
