鸟类的鸣叫被认为主要是在同性竞争、配偶吸引和伴侣的生殖刺激中起作用。然而，这些结论主要是基于对北温带物种中雄鸟歌声的研究。我们调查女性的歌曲在新热带区的鹪鹩，Thryophilus pleurostictus，通过观察和实验来测试女性歌曲的功能。雌性带纹弗伦斯的歌唱频率比雄性少得多，它们的歌曲较短，歌曲类型的曲目也较少。女性似乎没有唱的资源或配偶的同性竞争：女性的歌曲率并没有增加，在模拟入侵，和女性唱的响应不到三分之一的播放模拟领土入侵的未配对或配对的女性。对于常年占据多用途领地的物种来说，领地防御对于生存和繁殖都很重要，但女性参与领地防御的程度有限。女性更有可能接近模拟入侵者时，他们的合作伙伴更接近，更接近他们的合作伙伴在播放模拟一对入侵者，也许有助于防御共同与他们的合作伙伴。雌性似乎并没有用歌声来吸引雄性交配：只有25%的雌性在筑巢期间对模拟未配对雄性的播放做出回应，而且它们在产卵前不久不太可能唱歌，因为它们更有可能繁殖。带状弗伦斯的雌性歌声似乎主要用于与繁殖伙伴交流：雌性歌声重叠或在伴侣歌声的一秒内开始，这比预期的要多，而且雄性的声音行为会随着伴侣的歌声而改变。然而，带状弗伦斯中雌性鸣唱的比例很低，这表明这种功能并不选择鸣唱，这与同性竞争是雌性鸣唱的主要驱动力的观点一致。
Bird song is thought to function primarily in same-sex competition, mate attraction, and reproductive stimulation of a partner. However, these conclusions are based largely on studies of the song of male birds in north-temperate species. We investigate female song in a Neotropical wren, Thryophilus pleurostictus, using observations and experiments to test the function of female song. Female banded wrens sang much less often than males, their songs were shorter, and their repertoire of song types was smaller. Females did not seem to sing for same-sex competition for resources or mates: female song rate did not increase in response to simulated intrusion, and females sang in response to less than one-third of playbacks simulating territorial intrusion by either unpaired or paired females. Territorial defense is important for both survival and reproduction in species that occupy all-purpose territories year-round, but female involvement in territorial defense was limited. Females were more likely to approach simulated intruders when their partner approached more closely, and were closer to their partner during playback simulating a pair of intruders, perhaps contributing to defense jointly with their partner. Females did not appear to use song to attract males for mating: only 25% of females sang in response to playback simulating an unpaired male during the nest-building period, and they were less likely to sing shortly before laying when they were more likely to be fertile. Female song in banded wrens seemed to be used primarily for communicating with their breeding partner: female songs overlapped or began within one second of a song by their partner more often than expected by chance, and male vocal behavior changed in response to song by their partner. However, the low rate of female song in banded wrens suggests this function does not select for song elaboration, consistent with the view that same-sex competition is the main driver of female song elaboration.
