研究發現光污染會影響動物遷徙，包括鳥類、蝴蝶、飛蛾、蝙蝠等物種。 一些動物依靠星星來辨別方向，但光污染令牠們更難觀察星空； 亦有些動物會被市區的燈光影響而迷失方向或偏離遷徙路線，結果無法到達牠們的繁殖或覓食地點。 除了遷徙，光污染也會影響牠們的繁殖、覓食或休息行為。

New study found light pollution affects migrating animals including birds, butterflies, moths, bats and many more species. Some animals depend on stars to find directions, but light pollution makes it difficult for them to see the starry night sky; some will become disoriented by the lights from urban areas, went off route and might not make it to their breeding or feeding locations. beside migrations, light pollution also affects their breeding, feeding and resting behaviors.
