平尾弗伦斯（Pheugopedius euophrys）合作，以产生一个二重唱歌曲，其中男性和女性迅速交替唱歌音节。我们研究了如何使用来自每只鹪鹩的感官信息来协调个体之间的歌唱以产生这种合作行为。先前在非二重唱鸣禽物种中的发现表明，前运动回路应该编码每只鸟自己对二重唱的贡献。与此相反，我们发现，男性和女性弗伦斯编码的组合合作输出的对鸟。此外，行为和神经生理学表明，两性都根据伴侣的反馈来协调唱歌的时间，并表明女性可能会领导二重唱。
Plain-tailed wrens (Pheugopedius euophrys) cooperate to produce a duet song in which males and females rapidly alternate singing syllables. We examined how sensory information from each wren is used to coordinate singing between individuals for the production of this cooperative behavior. Previous findings in nonduetting songbird species suggest that premotor circuits should encode each bird's own contribution to the duet. In contrast, we find that both male and female wrens encode the combined cooperative output of the pair of birds. Further, behavior and neurophysiology show that both sexes coordinate the timing of their singing based on feedback from the partner and suggest that females may lead the duet.
