Mexican Pygmy Mouse

Also known as Southern Pygmy Mouse

Mexican pygmy mice are among the smallest rodents in North America, darting through dense grassy runways beneath arid scrub and agricultural borders. They maintain close monogamous pair bonds, sharing shallow subterranean nests woven from dry grass leaves and both participating in grooming and warming their tiny litters. Primarily crepuscular and nocturnal, they navigate complex surface trails with remarkable speed to forage for seeds before retreating from watchful predators.
