The Dark Kangaroo Mouse will live most of its life in burrows and emerge shortly after sunset to forage. Seeds are their primary source of food so they are known as “granivores,” but they will occasionally eat insects. They will forage by scratching and digging at sandy soil to expose seeds. They will collect the seeds in external cheek pouches to hoard for the winter months in their burrows. These mice are thought to have multiple litters per season, although their breeding habits are not well known. The average number of offspring is around four per litter but could be as high as seven or eight pups per litter. The breeding season spans from March to October. Being a smaller, ground-dwelling rodent makes the dark kangaroo mouse susceptible to predators. Common predators are foxes, badgers, owls, and rattlesnakes. Their dark coloring helps to camouflage them from predators as well their complex underground burrows can help them escape potential predators.
