发声行为在动物界很常见，在求偶和攻击中扮演重要角色，也是行为研究的常见课题。虽然许多物种的雌性会发声，但绝大多数行为研究都集中在雄性的展示上。我们研究了女性唱歌小鼠（Scotinomys teguina），小muroid啮齿动物，其中两性产生的歌曲组成的颤音的快速，向下的频率扫描的声音显示行为。先前的研究表明，雄性唱歌的老鼠会增加歌曲的产生，并在播放同种雄性歌曲时进行精确的反唱行为。我们测试了雌性唱歌的老鼠是否也会增加它们对雄性歌曲播放的反应，它们是否会反唱，以及在歌曲努力中是否存在性二态性。我们的研究结果表明，很像男性，女性唱歌的老鼠增加他们的歌曲努力和反唱响应男性歌曲的播放，但是，女性唱的歌曲少，短的男性相比。这项研究进一步通知女性发声行为的理解，并建立了一个有价值的模型，研究女性的声音显示唱歌的老鼠。
Vocal display behaviours are common throughout the animal kingdom, play important roles in both courtship and aggression, and are frequent subjects of behavioural research. Although females of many species vocalize, an overwhelming fraction of behavioural research has focused on male display. We investigated vocal display behaviours in female singing mice (Scotinomys teguina), small muroid rodents in which both sexes produce songs consisting of trills of rapid, downward frequency sweeps. Previous research established that male singing mice increase song production and engage in precisely timed counter-singing behaviour in response to playback of conspecific male song. We tested whether female singing mice also increased their rate of singing in response to playback of male song, whether they counter-sing, and whether there are sexual dimorphisms in song effort. Our results demonstrate that much like males, female singing mice increase their song effort and counter-sing in response to playback of male song; however, females sing fewer and shorter songs compared to males. This study further informs the understanding of female vocal behaviour and establishes the singing mouse as a valuable model for investigating female vocal display.
