Foraging movements of female bushy-tailed wood rats (Neotoma cinerea)

Abstract

Nocturnal foraging movements of female bushy-tailed wood rats (Neotoma cinerea) in the Canadian Rocky Mountains, Alberta, were monitored using radiotelemetry over two breeding seasons (1993–1994). Total distance moved and maximum foraging radius from the nest per night were calculated for individual females throughout the breeding season. Movements during pregnancy, lactation, and the postreproductive period did not differ significantly. Females moved much farther (up to 470 m) from the nest than previously reported for this species (60 m). Such long-distance movements may be related to the availability of an appropriate food supply.
