1. 由于工业扩张，荒野地区的人为噪音正在迅速增加。虽然许多道路研究试图评估工业噪音对鸟类的影响，但诸如边缘效应等相互矛盾的因素往往阻碍了得出有力结论的能力。我们对加拿大阿尔伯塔北部森林中产生噪声的压缩站周围区域与栖息地受到干扰但没有噪声的井台周围区域的雄性候鸟Seiurus aurocapilla配对成功率和年龄分布进行了比较。这使我们能够控制边缘效应、人类访问和其他因素，这些因素在道路产生的噪音研究中没有得到控制。采用广义估计方程（Generalized estimestimequations， GEE）分析了噪声对烤鸟配对成功率、年龄结构和身体形态的影响。我们发现，与无噪音井台相比，压缩机现场的炉鸟配对成功率（77%）显著降低（92%）。无论领地质量或个体雄性质量如何，这些差异都是明显的。在产生噪音的压缩站附近，首次繁殖的无经验鸟类明显多于无噪音的井台（48%比30%）。虽然对这些结果有多种近似的解释，但这些变化的最终原因似乎是噪音污染。我们假设噪音干扰了雄鸟的鸣叫，因此雌鸟在更远的地方可能听不到雄鸟的鸣叫，并且/或者雌鸟可能因为鸣叫特征的扭曲而认为雄鸟的鸣叫质量较低。合成与应用。这项工作表明，长期的背景噪音可能是影响鸟类种群的重要因素。它可以影响雀鸟配对成功和年龄结构；在阿尔伯塔北部，随着能源开发的迅速扩张，这可能会给某些物种带来问题。
1. Anthropogenic noise is rapidly increasing in wilderness areas as a result of industrial expansion. While many road studies have attempted to assess the effects of industrial noise on birds, conflicting factors such as edge effects often inhibit the ability to draw strong conclusions.2. We assessed pairing success and age distribution of male ovenbirds Seiurus aurocapilla in the boreal forest of Alberta, Canada, in areas around noise-generating compressor stations compared with areas around habitat-disturbed, but noiseless, wellpads. This allowed us to control for edge effects, human visitation and other factors that are not controlled for in studies of noise generated by roads. Generalized estimating equations (GEE) were used to assess the impacts of noise on ovenbird pairing success, age structure and body morphology.3. We found a significant reduction in ovenbird pairing success at compressor sites (77%) compared with noiseless wellpads (92%). These differences were apparent regardless of territory quality or individual male quality. Significantly more inexperienced birds breeding for the first time were found near noise-generating compressor stations than noiseless wellpads (48% vs. 30%).4. While there are multiple proximate explanations for these results, the ultimate cause of the changes seems to be noise pollution. We hypothesize that noise interferes with a male's song, such that females may not hear the male's song at greater distances and/or females may perceive males to be of lower quality because of distortion of song characteristics.5. Synthesis and applications. This work demonstrates that chronic background noise could be an important factor affecting bird populations. It can impact upon pairing success and age structure of passerines; in boreal Alberta this could pose a problem for certain species as energy development expands rapidly.
