斑胸草雀（Taeniopygia guttata）的歌曲音节通常包括谐波相关的频率成分。这些谐波可能会被抑制，并且这种差异强调在歌曲中的音节之间以及单个鸟类的歌曲之间变化。这些谐波抑制的模式就是音色。单个音节的谐波抑制模式在成年男性的歌曲中是恒定的。年轻的雄性会模仿年长雄性的歌声，也会模仿它们的和声抑制模式。注射管去神经支配扭曲了这些模式，这表明它们是通过主动控制发声器官产生的。对某些谐波的选择性抑制和强调为任何一个音节创造了大量可能的音色变体。这些增加了信号多样性的有限阵列的频率调制和范围内的基本频率发现斑马雀的歌曲。对鸟类鸣叫的分析如果不考虑音色，可能会忽略一个在声音交流中很重要的特征。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Zebra finch (Taeniopygia guttata) song syllables often include harmonically related frequency components. These harmonics may be suppressed, and this differential emphasis varies between the syllables in a song and between individual birds' songs. These patterns of harmonic suppression are timbre. Individual syllables' patterns of harmonic suppression are constant within adult males' songs. Young males that imitate the songs of older males also imitate their patterns of harmonic suppression. Syringeal denervation distorts these patterns, which suggests that they are produced through active control of the vocal organ. The selective suppression and emphasis of some harmonics creates a great number of possible timbre variants for any one syllable. These add signal diversity to the limited array of frequency modulations and range of fundamental frequencies found in zebra finch song. Analyses of bird song that disregard timbre may overlook a feature that is important in vocal communication.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
