| An inhabitant of the far north, the Barren Ground Shrew lives on the tundra from Point Barrow, Alaska, to the western shore of Hudson Bay, Canada. The fur on its back forms a well-defined brown stripe, and its sides and undersides are pale, a color pattern similar to the much larger Tundra Shrew. The tail has a small tuft on the end. Though much remains to be learned about the Barren Ground Shrew, it appears to prefer living in meadows of sedge-grass and thickets of dwarf willow and birch. It is similar to the Pribilof Island Shrew and the St. Lawrence Island Shrew, and the three species probably evolved from a common ancestor.
