鸟的二重唱是两个人的联合表演，通常是一对配偶，发出暂时协调的声音。二重唱有助于维持配偶关系、保护配偶或共同防御资源。然而，配偶之间的协调程度和不同的发声方式差别很大。虽然只有3% -4.3%的鸟类会二重唱，但这可能是因为研究通常集中在引人注目的二重唱上，而更多的私人形式的二重唱可能被忽视了。我们研究了野生斑胸草雀（Taeniopygia guttata）配偶之间的私人声音交流，斑胸草雀是一种群居的澳大利亚鸣禽，形成终生的伴侣关系。除了筑巢、孵化或孵蛋，伙伴们是分不开的。利用巢箱内的麦克风，监测了巢内伴侣之间的互动交流及其在不同繁殖阶段的变化。经过一段时间的分离，合作伙伴进行协调的相互声乐表演，包括特定的柔和的声乐元素，满足了用于定义二重唱的所有标准。此外，通过回放实验，我们获得了初步的结果，表明这些柔和的叫声可能允许配偶识别。因此，我们认为斑胸草雀在巢中的相互展示代表了私人的声乐二重唱，可能起着调节配偶关系维持的作用。(C) 2010动物行为研究协会。Elsevier Ltd.出版。版权所有。
Bird vocal duets are joint displays where two individuals, generally a mated pair, produce temporally coordinated vocalizations. Duets may contribute to pair bond maintenance, mate guarding or collaborative defence of resources. The degree of coordination between mates and the variety of vocalizations, however, vary considerably. Although only 3-4.3% of bird species have been reported to duet, this may be because studies have generally focused on conspicuous duets, and more private forms of duet might have been overlooked. We investigated private vocal communication between mates in wild zebra finches, Taeniopygia guttata, a gregarious Australian songbird that forms life-long pair bonds. The partners are inseparable unless nest building, incubating or brooding. Using microphones inside nestboxes, we monitored interactive communication between partners at the nest and its variation during different stages of breeding. After periods of separation, partners performed coordinated mutual vocal displays involving specific soft vocal elements that fulfilled all the criteria used to define duets. In addition, using playback experiments, we obtained preliminary results suggesting that these soft calls could allow mate recognition. Thus, we propose that mutual displays at the nest in zebra finches represent private vocal duets and may function to mediate pair bond maintenance.
