About the Northwestern Deermouse

The northwestern deer mouse, northwestern deermouse, or Keen's mouse (Peromyscus keeni) is a species of rodent in the family Cricetidae. It is a species of the genus Peromyscus, a closely related group of New World mice often called "deermice".

It is found in British Columbia in Canada and in Alaska and Washington in the United States. It was named after John Henry Keen in 1894. This type of rodent consumes and scatters seeds that are present in black bear scats. They also hoard seeds to store for winter survival.
