During a 47-month live-trap study conducted in a remnant grassland in west-central Kansas, Sigmodon hispidus preferred habitats with dense undergrowth and protective overstory and used less favored habitats primarily when population densities were high. Seasonal home ranges based on the exclusive boundary-strip method averaged significantly larger (P < 0.01) for males (0.96 acre) than for females (0.54 acre). Males were more nomadic than females, but both sexes traversed smaller areas during periods of high density than during low density. No indication of territorial defense was evident.
