捕获的欧椋鸟的歌曲连续几年记录，看看是否发生变化的歌曲曲目的大小和平均歌曲回合长度。九分之七的男性在他们录制的第二年唱新歌类型。三名男性，这是一岁时记录的第一次，增加了他们的平均歌曲回合长度显着，而平均歌曲回合长度的6个老年男性没有增加。三岁的男性也增加了他们的剧目大小显着超过六个老年男性。然而，六个年长的男性中有四个修改了他们的曲目。这些结果表明，椋鸟是“开放式”的学习者，但也表明，将新的歌曲类型到歌曲的能力随着年龄的增长而下降。此外，本研究亦探讨了四只笼养雄性椋鸟对鸣唱模式的选择。这四只雄鸟都从与它们共享鸟舍的成年雄鸟那里复制了很大一部分歌声。人工孵化的雄鸟经常从成年雄鸟那里复制不同类型的精确的歌曲序列。直接证据表明，椋鸟复制异种模仿其他椋鸟。
The song of captive Euroepan starlings was recorded in successive years to see if changes occurred in song repertoire size and average song bout length. Seven out of nine males sang new song types in their second year of recording. Three males, which were yearlings when recorded for the first time, increased their average song bout length significantly while the average song bout length of six older males did not increase. The three yearling males also increased their repertoire size significantly more than the six older males. Nevertheless, four of the six older males modified their repertoire. These results indicate that starlings are ‘open-ended’ learners, but also suggest that the ability to incorporate new song types into the song decreases with age. Choices of song models by four male starlings raised in captivity were also investigated. All four males copied a large proportion of their song from adult males with whom they shared the aviary. The captive-hatched males often copied precise sequences of different song types from the adult males. Direct evidence that starlings copy heterospecific imitations from other, starlings is also presented.
