抽象摘要。来自一个种群的雌性斑胸草雀（Taeniopygia guttata）可以在鸟舍中饲养的来自其自身种群的雄性、在鸟舍中饲养的来自不同种群的雄性或在没有成年歌唱导师的情况下饲养的来自其自身种群的雄性之间进行选择。来自与雌性相同种群的鸟舍饲养的雄性比来自同一种群的未经训练的雄性或来自不同种群的鸟舍饲养的雄性具有更高的繁殖成功率。作为歌曲模型的显着性与成年雄性的歌曲类型以及成年雄性羽翼未丰的幼崽总数有关。所有男性后代从其父亲的歌曲中抄袭的音节明显多于从其他人的歌曲中抄袭的音节，但未经训练的男性的儿子最不可能抄袭父亲以外的男性的音节。年轻的雄性从他们的父亲和其他雄性那里复制了未经训练的歌曲的特征。尽管未经训练的鸣叫与繁殖成功率较低有关，但它被年轻雄性接受为有效的鸣叫模式。
Abstract Abstract. Female zebra finches, Taeniopygia guttata , from one population were given a choice between males from their own population reared in aviaries, males from a different population reared in aviaries, or males from their own population reared without adult song tutors. Aviary-reared males from the same population as the females had higher reproductive success than did untutored males from the same population or aviary-reared males from a different population. Salience as a song model was related to the song type of the adult male as well as to the total number of young the adult male fledged. All male offspring copied significantly more syllables from their fathers' songs than from others' songs, but the sons of untutored males were the least likely to copy syllables from males other than their father. Young males copied qualities characteristic of untutored song both from their fathers and from other males. Although untutored song was associated with inferior reproductive success, it was accepted by young males as a valid song model.
