Conservation Status: Least Concern.

American Martens are widely distributed in northern forests across Canada and into Alaska. Only 200 years ago, they were also abundant in the southeastern United States. Smaller than the Fisher and larger than the Ermine, Martens are omnivores, including insects, fruits, and seeds as well as birds and small-to-medium-sized mammals in their diet. Martens most frequently hunt on the ground, but they are capable climbers, and will pursue Red Squirrels in trees. Martens are solitary and territorial.
