通常不唱歌的雌鸟拥有与雄鸟发声有关的脑核团。为了确定其中一个鸣唱核团（腹侧上纹状体（HVc）的尾侧核）是否在同种鸣唱感知中发挥作用，比较了雌性金丝雀对金丝雀和白冠麻雀鸣唱的求偶反应在HVc损伤前后。双侧病变的一部分HVC导致交配招标异种歌曲以及同种歌曲。控制女性继续只响应同种歌曲。这表明，HVc是至关重要的同种歌曲感知女性。因为雌性金丝雀通常不唱歌，所以雌性HVc中的神经元必须通过与雄性鸟类在歌曲感知运动理论中提出的机制不同的机制来发展反应选择性。
Female birds that do not normally sing possess brain nuclei associated with song production in males. To determine whether one song nucleus, the caudal nucleus of the ventral hyperstriatum (HVc), acts in conspecific song perception, courtship responses of female canaries to canary and white-crowned sparrow songs were compared before and after HVc lesions. Bilateral lesions of a portion of the HVc resulted in copulation solicitations to heterospecific song as well as conspecific song. Control females continued to respond only to conspecific song. This suggests that the HVc is critical for conspecific song perception in females. Because female canaries do not normally sing, neurons in female HVc must develop response selectivity by a mechanism different from that proposed for male birds in the motor theory of song perception.
