摘要一些成对的鸟会发出复杂而高度同步的二重唱我们通过实验研究了圈养的雄性弗伦斯是如何协调它们的二重唱的雄性会改变它们的歌声类型和时间来匹配雌性的歌声的播放鸟类的反应速度和精度表明了显着的认知能力成对的二重唱鸟可以唱出协调的二重唱，精度如此之高，以至于它们经常被误认为是一个单独的个体，然而，人们对这种令人印象深刻的时间同步是如何实现的知之甚少。我们通过实验研究了雄性快乐弗伦斯的二重唱协调性，通过在不同的距离和节奏下播放伴侣的歌曲短语进行短暂的圈养。男性更有可能对附近播放的歌曲做出反应，但不会改变其振幅以补偿其伴侣的模拟距离。男性修改他们的歌曲速率，以配合操纵的女性播放克里思，这表明他们倾听并回应每个女性的话语。每一只快乐的鹪鹩都有一个由大约40个不同的歌曲短语组成的特定性别的曲目，而成对的联合收割机则根据特定的二重唱“代码”来组合特定的短语，这对协调二重唱来说是一个进一步的挑战。我们发现，大多数男性产生适当的短语来回答女性播放歌曲的情况下，没有任何其他潜在的线索，有时提供正确的歌曲短语类型在0.5秒内开始的第一个女性播放听到。这些实验表明，快速决策和声乐生产，复杂的潜在的认知处理的指示，并提供了一种新的实验技术，调查机制控制声乐二重奏。
HighlightsSome pairs of birds produce complex and highly synchronized duet songsWe experimentally studied how captive male wrens coordinate their duet songsMales vary their song type and timing to match playback of their female's songsBirds respond with speed and precision indicative of remarkable cognitive abilitiesPairs of duetting birds can sing coordinated duets with such precision that they are often mistaken for a single individual, yet little is known about how this impressive temporal synchronization is achieved. We experimentally examined duet coordination in male happy wrens, held briefly in captivity, by playing song phrases from their partner at different distances and tempos. Males were more likely to respond to songs played nearby, but did not vary their amplitude to compensate for their partner's simulated distance. Males modified their song rate to match the manipulated female playback tempo, indicating that they listen and respond to each female utterance. Each happy wren has a sex-specific repertoire of about 40 different song phrases and pairs combine particular phrases according to pair-specific duet ‘codes’, creating a further challenge for coordinating duets. We found that most males produced the appropriate phrase to reply to the female playback song in the absence of any other potential cues, sometimes delivering the correct song phrase type within 0.5 s of the start of the very first female playback heard. These experiments demonstrate rapid decision making and vocal production, indicative of sophisticated underlying cognitive processing, and provide a novel experimental technique to investigate the mechanisms controlling vocal duets.
