声学信号在影响运动和社会互动方面至关重要。在具有动态社会结构的物种中,例如多层次的社会,声音信号可以提供一种关键机制,允许个人识别和发现或避免彼此并交换信息。然而,如果个体之间的间隔经常超过最大信号范围,运动和信号之间的关系变得更加复杂。作为圈养中研究最好的鸣鸟,斑马雀(Taeniopygiacastanotis)是一个物种,具有独特的歌曲,可以在几米范围内听到,并且是野外广泛的动态多层次社会组织,对其歌曲在社会凝聚力和协调中的实际作用提出了质疑。这里,我们概述了社会组织(网络)中的鸟鸣,并利用斑马雀和男性歌曲的生态来讨论唱歌如何促进信号范围很短的物种的社会凝聚力和协调。我们提出了斑马雀在多大程度上是代表物种的问题,以理解歌曲在交流中的功能,我们扩大了目前对鸟鸣功能及其个人签名的看法。本文是“声音的力量:揭示声音交流如何塑造群体动力学”主题的一部分。
Acoustic signalling is crucial in affecting movements and in social interactions. In species with dynamic social structures, such as multi-level societies, acoustic signals can provide a key mechanism allowing individuals to identify and find or avoid each other and to exchange information. Yet, if the spacing between individuals regularly exceeds the maximum signalling range, the relation between movements and signals becomes more complex. As the best-studied songbird in captivity, the zebra finch (Taeniopygia castanotis) is a species with individually distinct songs that are audible over just a few metres and a widely ranging dynamic multi-level social organization in the wild, raising questions on the actual role of its song in social cohesion and coordination. Here, we provide an overview of
birdsong in social organizations (networks) and use the ecology of the zebra finch and male song to discuss how singing can facilitate social cohesion and coordination in species where the signal range is very short. We raise the question of the extent to which zebra finches are a representative species to understand the function of song in communication, and we broaden current views on the function of
birdsong and its individual signature. This article is part of the theme issue \'The power of sound: unravelling how acoustic communication shapes group dynamics\'.
