We found that the call frequency in both exhalation and inhalation phrases in male advertising calls differed between the two subspecies. Further, we conducted a reciprocal playback experiment to examine how females at the two geographical locations respond to the local and non-local male calls. Females tended to approach towards their regional calls, indicating that females recognize and might prefer their local male calls. Interestingly, E. minor iredalei females responded vocally to their local calls and took a longer time when approaching, while E. minor minor females did not use any vocalization during the approach and selected their local calls within a shorter time. However, given our limited sample size, we cannot exclude the possibility that these observed differences might be due to individual differences. Thus, further research is required to evaluate whether male mating signals and female responses to the male calls have diverged between the two subspecies.
