Abstract: From July to August, 2005, sixty-three individuals of Myotis siligorensis were captured in Shuanghe township (102°20’E, 24°30’N), Yunnan province, China. The echolocation calls of M. siligorensis were recorded using UltraSound detector D980 (Pettersson Elektronik AB) and the characteristics of calls were analyzed with Batsound 3.10 (Version 3.10 Pettersson Elektronik,UK). The results show that frequency-modulated (FM) calls with 1~3 harmonics were emitted by M. siligorensis, which indicated that the pulse duration, inter-pulse interval and duty cycle were significantly different at flying, crawling and handing states, respectively. The terminal frequency of 1st harmonic, bandwidth, pulse duration and duty cycle were significantly different between male and female by means of One-Way ANOVA. Different characteristics of echolocation calls of M. siligorensis might reveal the adaptation to their prey strategies and foraging habitats.
