人为噪声是与人类密切接触的动物必须应对的最严重问题之一，因为它会干扰从发射器发送到接收器的声学信号中编码的信息传输。鸣叫复杂的鸟类特别容易受到人为噪音的影响。本研究分析了知更鸟 Erithacus rubecula 的鸣叫对许多栖息地参数和交通噪声幅度的选择性。结果表明，鸟类会采取积极措施，避免在繁忙道路附近的声音交流受到干扰。在喧闹的领地上，雄性会在离地面较高的栖息处唱歌。这是第一份证明普通雀形目鸟类歌柱高度与交通噪音水平之间相关性的报告。在过度噪音污染的环境中，选择位于植被较高处的栖息地很可能会改善知更鸟对邻近竞争对手的听觉感知。高强度和低强度噪声区域之间歌帖位置选择性的差异可能会给相关个人带来严重后果。 (C) 2014 Elsevier Ltd. 保留所有权利。
The man-made noise is one of the most serious problems that animals living in close contact with humans have to contend with, as it interferes with the transmission of information encoded in acoustic signals sent from emitter to receiver. Birds with their complex songs are particularly vulnerable to anthropogenic noise. This research analyses the selectivity of song posts of the robin Erithacus rubecula with respect to a number of habitat parameters and the traffic noise amplitude. The results indicate that the birds take active steps to avoid interference to their vocal communication in the vicinity of busy roads. The males in noisy territories sang from perches located higher above the ground. This is the first report to demonstrate the correlation between song post height and traffic noise levels in a common passerine bird. Very likely, the choice of perches situated higher up in the vegetation improves the robins' auditory perception of neighbouring rivals in an environment polluted by excessive noise levels. The differences in selectivity of song post location between areas with high and low intensities of noise may have serious consequences for the individuals concerned. (C) 2014 Elsevier Ltd.
