    Echolocation calls of the two endemic leaf-nosed bats (Chiroptera: Yinpterochiroptera: Hipposideridae) of India: Hipposideros hypophyllus Kock & Bhat, 1994 and Hipposideros durgadasi Khajuria, 1970
    Journal Article
    We provide the echolocation call characteristics of two endemic Hipposiderid bats, the Kolar Leaf-nosed Bat Hipposideros hypophyllus and Durga Das’s Leaf-nosed Bat H. durgadasi from Kolar district, Karnataka, India for the first time. The calls consisted of a constant frequency (CF) component followed by a frequency modulated (FM) tail. It was found that, on comparison with the call frequencies of other members of the bicolor group of the genus Hipposideros previously reported from different parts of southeast Asia, H. durgadasi, though larger than H. cineraceus, called at a much higher frequency (168.4 – 175.7 kHz). H. hypophyllus, on the other hand, called between 103.0 – 106.4 kHz. In this paper we present our findings and analysis of the calls of these endemic species.
