Abstract:

I studied a colony of rock squirrels (Spermophilus variegatus) in the Texas Hill Country from February to October, 1979. The number of residents varied from 8 to 29. A single male was resident from February until late May, and most female home ranges were encompassed by the male's territory. Six females produced 23 young: 14 females and 9 males. Females with litters restricted their activities to areas near the natal burrow and were territorial toward other adult females. Dispersing young left the colony site approximately 3 months after they emerged from the natal burrows. During the breeding period, adults of both sexes exhibited considerable movement.
