The vocalisations of female songbirds are more complex, widespread, and functionally important than previously thought; yet information is still depauperate compared to that of males. Here we provide the first recordings and analysis of the vocal behaviour of female Albert's lyrebirds, a species in which males are known for elaborate song and dance displays involving vocal mimicry. We document one female Albert's lyrebird vocalising during nest construction and another vocalising at a nest containing a nestling and find that, like males, female Albert's lyrebirds produce vocal mimicry, conspecific song, and alarm calls. However, female repertoires are both distinct from those of the males and used during female-specific contexts. Our results highlight the potential complexity of vocalisations produced by female songbirds and add to a small but growing list of species in which females produce vocal mimicry.
雌性鸣禽的发声比之前认为的更为复杂、广泛且在功能上更重要;然而与雄性相比,相关信息仍然匮乏。在此,我们首次记录并分析了阿尔伯特琴鸟雌性的发声行为,该物种的雄性以涉及声音模仿的精致歌声和舞蹈展示而闻名。我们记录到一只雌性阿尔伯特琴鸟在筑巢时发声,另一只在有雏鸟的巢边发声,并且发现,与雄性一样,雌性阿尔伯特琴鸟也会发出声音模仿、同种歌声和警报叫声。然而,雌性的全部发声曲目既不同于雄性,且是在特定雌性情境中使用。我们的结果凸显了雌性鸣禽发声的潜在复杂性,并为雌性发出声音模仿的物种清单增添了一员,尽管该清单规模较小,但在不断增加。
