对靛蓝雀和青雀的杂交半种（雀形目，P.amoena）在异域和同域种群中的鸣唱进行了研究。在allopatry，这两个物种的男性反应强烈，同种和异种歌曲弱。在同域生活中，靛蓝、天青石和杂交雄性对靛蓝和天青石歌曲的反应同样强烈。歌曲结构的改变，提出靛蓝色的时间模式和靛蓝色的时间模式的靛蓝色的音节，表明异域靛蓝色和天青石男性的反应主要是由测试歌曲的音节（语音）线索，而不是由时间模式。同域性和异域性雄性反应的总体模式提供了一些了解这些物种之间的生殖隔离的程度。
The hybridizing semispecies indigo and lazuli buntings (Passerina cyanea, P. amoena) were studied in song playback experiments in allopatric and sympatric populations. In allopatry, males of both species responded strongly to conspecific and weakly to heterospecific songs. In sympatry, indigo, lazuli and hybrid males reacted equally and strongly to both indigo and lazuli songs. Alteration of song structures, by presenting indigo syllables in lazuli temporal pattern and lazuli syllables in indigo temporal pattern, showed that the response of allopatric indigo and lazuli males was determined primarily by syllabic (phonological) cues in the test songs and not by the temporal pattern. The overall pattern of male response in sympatry and allopatry provides some understanding of the observed degree of reproductive isolation between these species.
