Pattern of habitat utilization, home range and food habits of a raccoon dog are studied in a small islet, Takashima, western Kyushu. The home range and the number of individuals in the area are established by means of a bait-marking method which is a new technique developed in this study taking notice of the peculiar behaviour or the raccoon dog to defecate its feces daily on a definite fecal pile site. The size of home range estimated by the method ranged from 1.1 to 4.3 ha (2.8 ha av.) and the total number of individuals in this islet was 8.6-16.1,0.46-0.86 per ha in density. The individual home ranges overlapped closely to each in four seasons. The small population size and high population density in this islet are explained by the confined circumstances of habitat in the one hand and by the specific modes of life of the raccoon dog, that they can live together in a small area with cooperative utilization of the habitat on the other.
