Pine martens have long, bushy tails, one-third the length of their body. Fishers live in similar habitat, have similar tracks and are darker in color than pine martens. Stone martens are non-native species and are also about the size of the male pine marten. They are pale gray to brown with a white throat patch. They'll pursue prey, red squirrels or chipmunks, up a tree and may climb trees to escape danger.
Martens move across the ground in a zig-zag fashion, then take a series of jumps.
