The California Mouse is the largest Peromyscus in the United States and is notable for being monogamous, with males providing extensive biparental care—a rarity among rodents. Pairs occupy shared home ranges and fathers play an active role in keeping pups warm and grooming them. It is found in chaparral and oak woodlands along the California coast.
