沼泽莺(Cistothorus Palustris)的歌声是一种代代相传的习得特征。来自加利福尼亚州和纽约[美国]的雄性沼泽乌鸦分别学习大约150和50种不同的歌曲。在歌唱曲目较多的人群中，参与歌唱控制的两个端脑核团--纹状体腹侧上核、尾侧部和弓状体粗壮核的体积分别平均大40%和30%。
The song of marsh wrens (Cistothorus palustris) is a learned trait passed on from generation to generation. Male marsh wrens from California and New York [USA] learn about 150 and 50 different song apiece, respectively. The volumes of the hyperstriatum ventralis, pars caudalis and the robust nucleus of the archistriatum, 2 telencephalic nuclei involved in song control, are larger by an average of 40% and 30%, respectively, in the population with a larger song repertoire.
