夜间人造光（ALAN）正在对全球自然系统产生不利影响，包括ALAN对迁徙鸟类的迷失方向影响。了解ALAN趋势如何在物种的季节性分布中发展，将为缓解措施提供信息，例如熄灯计划。在这里，我们交叉ALAN年度趋势估计（1992 - 2013）与每周估计的相对丰度为42 perturnally迁移雀形目鸟类在北美繁殖，使用从eBird社区科学数据库的观察合并期间2005 - 2020。我们使用聚类分析，以确定与ALAN趋势类似的每周协会的物种。我们的研究结果确定了三个突出的集群。其中两个包含在繁殖季节发生在北美东北部和西部的物种。这些物种与中等ALAN水平和弱负ALAN趋势在繁殖季节，低ALAN水平和强正ALAN趋势在非繁殖季节。繁殖和非繁殖季节之间的差异是较低的物种发生在南美洲北方和中美洲的物种发生在非繁殖季节。对于非繁殖期发生在南美洲的物种，
Artificial light at night (ALAN) is adversely affecting natural systems worldwide, including the disorienting influence of ALAN on nocturnally migrating birds. Understanding how ALAN trends are developing across species ’ seasonal distributions will inform mitigation efforts, such as Lights Out programs. Here, we intersect ALAN annual trend estimates (1992 – 2013) with weekly estimates of relative abundance for 42 nocturnally migrating passerine bird species that breed in North America using observations from the eBird community science database for the combined period 2005 – 2020. We use a cluster analysis to identify species with similar weekly associations with ALAN trends. Our results identified three prominent clusters. Two contained species that occurred in northeastern and western North America during the breeding season. These species were associated with moderate ALAN levels and weak negative ALAN trends during the breeding season, and low ALAN levels and strong positive ALAN trends during the nonbreeding season. The difference between the breeding and nonbreeding seasons was lower for species that occurred in northern South America and greater for species that occurred in Central America during the nonbreeding season. For species that occurred in South America during the nonbreeding
