Abstract: From September to November 2007,we recorded and analyzed the echolocation calls of Ricketti’s big-footed bat (Myotis ricketti),in call-recording cages using BatSound software. We also calculated measurements of wing shape for these bats. We compared the parameters of echolocation calls and wing shape between males and females. The results showed that only the interpulse interval was significantly different between males (68.49 ± 10.99 ms) and females (83.61 ± 13.77 ms)(t-test:t = -2.72,P <0. 01),while the pulse duration (male:4.28 ± 0.34 ms,female:4.64 ±0. 97 ms),the dominant frequency(40. 31 ± 1.36 kHz,40.20 ± 1. 32 kHz),the max frequency (72.40 ± 2. 37 kHz, 72.20 ±2.66 kHz),the min frequency (29. 00 ± 1.16 kHz,28. 60 ± 1.58 kHz),and the measurements of wing shape were not significantly different between males and females. M.ricketti had average wing loading(male:8. 61 ±0.72 N /m2 ,female:8.51 ± 0.81 N/ m2 ),high aspect ratio (7. 96 ± 0. 31,8. 09 ± 0.34)and high wing tip shape index (2. 93 ± 1.09,2.48 ±1.02).
