breeding
Breeding. Breeding occurs only once a year, soon after emergence from hibernation. A litter of 1 - 13 young (average 9 - 4) is born within burrow. Young weigh 2 - 2 - 5 - 1 g each (averages of 3 - 3 g, 3 - 7 g, and 3 - 9 g in different locations). Juveniles emerge from the burrow four weeks after birth, in late March or April, and females reach sexual maturity at one year of age. Females produce only one litter a year. Due to differential reproductive strategy, males and females also have differences in growth rate and annual weight cycles.
