Comments

Several individuals were captured at caves at Marang (Gua Sungai) and Tintang (Gua Kelelawar) formations. It is the largest of the Bornean Hipposideros and is known to roost in large cave colonies in limestone areas or small groups in hollow trees. It is distributed throughout much of Borneo and is represented in each state at several localities (Boitani et al., 2006).
