| Harvest mice are nocturnal and active year-round. They are good climbers. On the ground, they often use runways made by other small mammals. Grass seeds form a large part of their diet. They find seeds on the ground or bend the stems to get the seeds. They also eat some green leaves and occasionally insects. They are not usually thought to be a threat to agriculture. Zacatecan Harvest Mice are found only in Mexico, in Chihuahua and Michoacán.
