Food Habits
Forbs apparently a primary food. Also uses grasses, shrubs, insects, and other arthropods. Cannibalism of road-killed conspecifics and consumption of other carrion has been observed.
Ecology
Can hybridize with S. richardsonii . Males emerge from hibernation before females and establish a behavioral dominance. Hierarchical distribution of territories. May consume agricultural crops.
Reproductive Characteristics
Adult and yearling females produce 5 to 7 young per litter. Appear above ground at 4 to 5 weeks of age. Yearlings may not reproduce when in poor condition. Breeding probably occurs late March to mid-April.
