多模式信令可以改善或最大化信息交换。一个挑战是要证明两个独立的信号，如发声和视觉显示，是故意协调的。雄性斑马雀在求爱过程中发出视觉和听觉信号，一边唱歌一边表演刻板的舞蹈。雄性靠近雌性，以之字形跳跃，转动身体轴线，在栖息处或以上反复擦拭喙。之前对斑马雀歌舞编排的唯一定量研究显示，在歌唱过程中，所有动作的分布在鸟类中并不强烈，但在父亲和儿子身上非常相似。这增加了特定动作可能遵循编排的可能性。在这里，我们报告了三个可操作定义的舞蹈动作，‘嘴擦拭’(BA)、‘转身’(TA)和‘跳跃’，它们在歌唱时的频率和速度与在静默中不同。BW、TA和Hop在歌赛开始和结束时显著聚集，并以非随机的方式排列。此外，BW，而不是TA，在歌唱时比非歌唱时表现得更快。最后，在特定音符的情况下，啤酒花的巧合频率比预期要高得多。总而言之，这些结果表明，雄性斑马雀在求偶过程中会结合歌舞。这可能有助于雌性在嘈杂的环境中识别求爱的雄性，并评估求偶的强度和质量。我们的结果强调了动作手势与学习发声的编排，例如伴随语音的手势，是人类和鸟类信号之间的进一步相似之处。他们邀请未来研究潜在的神经机制和配偶选择的后果。(C)2015年动物行为研究协会。爱思唯尔有限公司出版。保留所有权利。
Multimodal signalling can improve or maximize information exchange. A challenge is to show that two independent signals, such as vocalizations and visual displays, are deliberately coordinated. Male zebra finches, Taeniopygia guttata, signal visually and acoustically during courtship, performing a stereotyped dance while singing. The male approaches the female hopping in a zig-zag pattern, turning his body axis, and wiping his beak repeatedly on or above the perch. The only previous quantitative study of song and dance choreography in zebra finches revealed that the distribution of all movements during song was not strongly patterned across birds but very similar in fathers and sons. This raises the possibility that particular movements may follow a choreography. Here we report that three operationally defined dance movements, 'beak wipe' (BA), 'turn-around' (TA) and 'hop', occurred with different frequencies and speed during singing than during silence. BW, TA and hops clustered significantly at the start and end of song bouts and were arranged in a nonrandom fashion. In addition, BW, but not TA, were performed faster during song than nonsong. Finally, hops coincided significantly more often than expected by chance with particular notes. Together, these results suggest that male zebra finches integrate their song and dance during courtship. This may help females to identify courting males in a noisy environment and evaluate the intensity and quality of the courtship performance. Our results underscore that the choreography of movement gestures with learned vocalizations, such as hand gestures accompanying speech, is a further parallel between human and avian signalling. They invite future investigations into the underlying neural mechanisms and consequences for mate choice. (C) 2015 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd.
