In New Mexico, Ord's kangaroo rat annual home ranges in mesquite averaged 3.35 acres (1.36 ha). In Nevada sagebrush/grassland, Ord's kangaroo rat home ranges were estimated as 1.53 acres (0.62 ha) by the circular method and 1.06 acres (0.43 ha) by the principal component method. Home range movements increased through spring and again in late fall and early winter. No significant difference was found between male and female Ord's kangaroo rat home ranges; however, female home ranges decreased during reproductive periods. Recapture data for Ord's kangaroo rats in Arizona indicated they do not travel far from the home range; most Ord's kangaroo rats were recaptured within 165 ft (50 m) of the original capture site. Data on the lifetime movements of individuals indicated most were recaptured within 330 feet (100 m) of the original capture site.
