Movement data collected during a 9-year live-trapping study of Sigmodon hispidus in northeastern Kansas were analyzed using three indices of home range size: 1) distance between successive captures; 2) mean squared distance from center of activity; and 3) S∞ Results obtained from the three indices generally were consistent. Reproductively mature adult and subadult males occupied larger home ranges than their nonreproductive counterparts. Reproductive females showed the same tendency, but the differences were not statistically significant. Adult males inhabiting a more sparsely populated abandoned pasture displayed larger home ranges than did those in an old field. These patterns of Sigmodon movements were comparable to trends reported in other geographic localities. Independence between successive capture locations, a requirement for the analysis of movement data using routine statistical techniques, was observed for 86% of all individuals.
