Abstract: Shortnosed fruit bat Cynopterus sphinx angulatusis known to roost under ‘tents’ constructed from the modified fronds of Chinese fan-palmLivistona chinensis. In this study, the distribution and habitat selection of C. sphinx angulatus in Guangzhou City were investigated from September 2006 to March 2007. A total of 45 ‘tents’ were observed, of which, 26 ‘tents’ revealed the presence of roosting. It was revealed that C. sphinx angulatus had a specific preference for roosting under the fronds of L. chinensis. Importantly, the habitat of C. sphinx angulatus overlapped heavily with the areas of human activity. A total of 18 roosting groups were captured, of which, 5 groups were captured in whole, and 13 groups in part. 17 of the groups, accounting for 94% of the total, contained at least one male. Of the 5 groups captured in whole, two were polygynous, one was monogamous, one contained a solitary male, and another contained bachelor males.
