The echolocation calls were recorded using UltraSound Detector when the bats were in the following three situations: hanging freely, flying in a large cage, and flying in a small cage. The pulse duration (PD), dominant frequency (DF), and inter-pulse interval (PI) were analyzed using BatSound Pro-Sound Analysis software. We used GLM ANOVA to analyze the call differences among different situations. H. larvatus emitted echolocation calls with the highest DF when hanging freely and with the lowest DF when flying in the large cage. The highest PD and PI of calls of both hipposiderid bats were found when they were hanging freely and the lowest values were found in the small cage. Our results indicated that the echolocation calls of bats would change according to the situations and habitats and confirmed the plasticity of echolocation calls in bats.
