Expansion of anthropogenic noise and night lighting across our planet 1 , 2 is of increasing conservation concern 3 – 6 . Despite growing knowledge of physiological and behavioural responses to these stimuli from single-species and local-scale studies, whether these pollutants affect fitness is less clear, as is how and why species vary in their sensitivity to these anthropic stressors. Here we leverage a large citizen science dataset paired with high-resolution noise and light data from across the contiguous United States to assess how these stimuli affect reproductive success in 142 bird species. We find responses to both sensory pollutants linked to the functional traits and habitat affiliations of species. For example, overall nest success was negatively correlated with noise among birds in closed environments. Species-specific changes in reproductive timing and hatching success in response to noise exposure were explained by vocalization frequency, nesting location and diet. Additionally, increased light-gathering ability of species’ eyes was associated with stronger advancements in reproductive timing in response to light exposure, potentially creating phenological mismatches 7 . Unexpectedly, better light-gathering ability was linked to reduced clutch failure and increased overall nest success in response to light exposure, raising important questions about how responses to sensory pollutants counteract or exacerbate responses to other aspects of global change, such as climate warming. These findings demonstrate that anthropogenic noise and light can substantially affect breeding bird phenology and fitness, and underscore the need to consider sensory pollutants alongside traditional dimensions of the environment that typically inform biodiversity conservation. Human-generated noise and night lighting affect breeding habits and fitness in birds, implying that sensory pollutants must be considered alongside other environmental factors in assessing biodiversity conservation.

感官污染物改变了整个大陆的鸟类物候和健康状况

人为噪声和夜间照明在我们星球上的扩展 1、2 引起了越来越多的保护关注 3-6。尽管从单一物种和局部规模的研究中越来越多地了解对这些刺激的生理和行为反应,但这些污染物是否影响健康还不太清楚,物种对这些人为压力源的敏感性如何以及为何不同。在这里,我们利用大型公民科学数据集以及来自美国本土的高分辨率噪声和光数据来评估这些刺激如何影响 142 种鸟类的繁殖成功。我们发现对与功能特征和物种栖息地关系相关的感官污染物的反应。例如,整体巢穴成功与封闭环境中鸟类的噪音呈负相关。响应于噪音暴露的繁殖时间和孵化成功的物种特异性变化可以通过发声频率、筑巢位置和饮食来解释。此外,物种眼睛的聚光能力增加与响应光照的生殖时间的更强进步有关,可能会造成物候不匹配 7。出乎意料的是,更好的聚光能力与减少离合器故障和增加对光照的整体巢穴成功有关,提出了关于对感官污染物的反应如何抵消或加剧对全球变化其他方面(如气候变暖)的反应的重要问题。这些发现表明,人为噪音和光线可以显着影响种鸟的物候和健康,并强调需要考虑感官污染物以及通常为生物多样性保护提供信息的传统环境维度。人类产生的噪音和夜间照明会影响鸟类的繁殖习性和健康状况,这意味着在评估生物多样性保护时,必须将感官污染物与其他环境因素一起考虑。
