For Townsend's Ground Squirrel,
A nest of grass, sagebrush, and other materials are located in the burrow system, which may be up to 15 m (50 ft) long and 1.8 m (6 ft) deep. Mating occurs soon after activity begins (January through March). Gestation period is 23 or more, days; the young are born in February through April. Average litter sizes reported include 9 (range 4-16) and 4.8 (Svihla 1939). One litter is produced per year. The young are weaned in 35 days and reproduce as yearlings.
For Washington ground squirrel,
Mates late January to early February. 1 litter per year of 5-11 young (average 8) born in mid-March; gestation is probably about 28 days.
