Spatial data were collected in a population of individually marked nine-banded armadillos (Dasypus novemcinctus) at a site in Florida from 1992–1995. Approximately ⅓ of the animals (118/313) were sighted more than once. Data on distances moved between successive sightings showed that armadillos moved <200 m both within and between years. However, animals moved significantly farther between than within years. The average distance between sightings was significantly longer for adults than for juveniles within, but not between, years. There were no sex differences in distances moved within or between years for either adults or juveniles. Analyses of distances to nearest neighbors showed that adults were closer to one another than to juveniles and that juveniles of the same sex were closer to one another than to juveniles of the opposite sex. This latter result probably reflects maintenance of proximity among littermates.
