Abstract

Traffic noise is a pervasive pollutant that affects wildlife at individual and group levels through mechanisms such as disrupting communication, affecting antipredator strategy, and/or changing how they use space within a habitat. Urbanization is expanding rapidly—few places remain untouched by anthropogenic noise disturbance—so understanding the implications of noise on wildlife behavior is paramount to conservation efforts. We asked whether traffic noise could change space use and social network metrics in flocks of captive birds. Specifically, we quantified the effects of playbacks of traffic noise on individual sociality (weighted degree, number of social partners weighted by the frequency of interactions with those social partners) and flock clustering (global clustering coefficient, connectivity of neighbors). In this study, we recorded social interactions and space use of flocks of captive zebra finches (Taeniopygia guttata) before, during, and after an experimental traffic noise introduction in two treatments: high- and lower-amplitude noise. Our results demonstrated that individual sociality and flock clustering increased in response to the noise introduction in both high-amplitude and low-amplitude treatments. Additionally, birds in the high-amplitude treatment spent more time in the room with active playback during noise playback whereas birds in the lower-amplitude treatment decreased time spent in the room closest to the high-amplitude treatment. Increased social behavior in response to traffic noise could influence disease transmission, social learning, and mating dynamics. We suggest future studies explore the mechanisms driving increased social behavior in traffic noise, such as perceived predation risk, vigilance, and cross-sensory interference.

斑马雀在交通噪声中增加社交行为:对城市鸣禽的启示
摘要 交通噪声是一种普遍存在的污染物,通过破坏交流、影响反捕食策略和/或改变栖息地空间利用方式等机制,在个体和群体层面对野生动物产生影响。城市化正在迅速扩张,很少有地方不受人为噪声干扰,因此了解噪声对野生动物行为的影响对保护工作至关重要。我们想知道交通噪声是否会改变圈养鸟类的空间利用和社会网络指标。具体来说,我们量化了交通噪声回放对个体社会性(加权程度,根据与这些社会伙伴的互动频率加权的社会伙伴数量)和鸟群聚类(全局聚类系数,邻居的连通性)的影响。在这项研究中,我们记录了人工饲养斑马雀(Taeniopygia guttata)在实验性交通噪声引入之前、期间和之后的社会互动和空间利用情况。我们的研究结果表明,在高振幅和低振幅处理中,个体的社会性和鸟群的集群性都随着噪声的引入而增加。此外,在噪声重放期间,高振幅处理的鸟类在主动重放的房间里花费的时间更多,而低振幅处理的鸟类在最靠近高振幅处理的房间里花费的时间减少。对交通噪声反应的社会行为增加可能会影响疾病传播、社会学习和交配动态。我们建议未来的研究探索交通噪声下社会行为增加的驱动机制,如感知到的捕食风险、警惕性和跨感官干扰。

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
