Western harvest mouse
(重定向自Reithrodontomys megalotis)

The western harvest mouse (Reithrodontomys megalotis) is a small neotomine mouse native to most of the western United States. Its range extends from southwest British Columbia and southeast Alberta continuously to west Texas, northeast Arkansas, northwest Indiana, southwest Wisconsin, and the interior of Mexico to Oaxaca. Many authorities consider the endangered salt marsh harvest mouse to be a subspecies, but the two are now usually treated separately.
