| Harvest mice often build their baseball-sized nests above the ground, in vegetation. The nests are woven of grass and often house a pair of mice, who plug the entrance when they are within. Unlike most other small rodents, harvest mice tend not to be territorial. Volcano Harvest Mice live high in Mexico's volcano belt, the Cordillera Neovolcanica.
