Pinyon mouse

The pinyon mouse (Peromyscus truei) is native to the southwestern United States and Baja California in Mexico. These medium-sized mice are often distinguished by their relatively large ears. The range of this species extends from southern Oregon and Wyoming in the north, and extends south to roughly the U.S.-Mexico border, with a disjunct population known as the Palo Duro mouse (Peromyscus truei comanche) that occupies an area in the vicinity of Palo Duro Canyon in the Texas panhandle.
