我们测试的能力，1岁的欧洲椋鸟（Sturnus vulgaris）收购歌曲，而在不同的生理状态。光不应男性，低睾酮水平，学习歌曲完全和准确的感光男性在充分的生殖条件。这表明，歌曲收购在1岁的男性并不依赖于高水平的雄激素。在非繁殖季节学习歌曲的能力可能反映了高的歌曲输出的潜在导师通过大部分的一年，包括光不应期，并可能促进歌曲曲目的大小在成年期的增加。
We tested the ability of 1-year-old European starlings (Sturnus vulgaris) to acquire songs while in different physiological states. Photorefractory males, with low testosterone levels, learned songs as completely and as accurately as photosensitive males in full reproductive condition. This indicates that song acquisition in 1-year-old males does not depend on high levels of androgens. The ability to learn songs during the nonbreeding season may reflect the high song output of potential tutors through most of the year, including the photorefractory period, and may facilitate increases in song repertoire size in adulthood.
