Movements of Feral House Mice in Agricultural Landscapes

Abstract

From September 1992 to May 1993 we radio-collared 155 house mice (Mus domesticus) on agricultural fields in southern Queensland to measure movements and to determine social organisation. During the breeding season most individuals were site-attached and home ranges of both sexes overlapped extensively. There was no sign of exclusive space use for breeding individuals. Breeding males had home ranges that were larger than those of breeding females (0.035 ha v. 0.015 ha), and moved about more. After breeding ended, home ranges increased over tenfold in area, and most mice became nomadic and not site-attached.
