Home ranges, areas of intensive use, and locations of nest sites were determined for female Columbian ground squirrels and their daughters over seven years from a low-density population in southwestern Alberta. Adult females usually retained similar home ranges from year to year. However, they moved their nest sites more often than expected in years when a yearling daughter was present. Core areas and centres of activity also changed when the nest site was moved. Most daughters settled on their natal areas. The relinquishing of nest sites by females to their daughters is seen as a form of parental investment.
