Abstract:

We investigated the foraging area of three individuals (2 males and 1 female) of Short-nosed Fruit Bat, Cynopterus sphinx (Chiroptera, Pteropodidae) in Luhuan, Macau from May 2015 to December 2015 using radio telemetry. The results found that the monthly mean foraging area among these three individuals was significantly different (F3,23 = 77.854，P < 0.000 1) (Table 1). Two males had smaller foraging areas, 1.6 ± 0.4 hm2 and 17.9 ± 6.6 hm2 (both n = 8), respectively; while the female had bigger one, 31.7 ± 4.7 hm2 (n = 7) (Fig. 2). The average distance between the daytime roosting site and foraging sites among three individuals was also significantly different (F3,23 = 16.034，P < 0.001), those of two males were 53.6 ± 12.4 m and 446.2 ± 68.8 m (both n = 8), while that of female was 606.9 ± 94.7 m (n = 7). The foraging area of one male partly overlapped with that of another, but that of female was separate from those of two males. Furthermore, the foraging area varied in different month, those in winter (November and December) were relative lager, and that of female in October was smaller than those in September and November (Fig. 3). The results of this study suggested that the foraging sites of Short-nosed Fruit Bat normally close to their daytime roosts, and they have moderate foraging area, which presents seasonal variation.
