Global noise pollution harms birds by disrupting communication and breeding, especially in urban and ground-nesting species, a study of 160 species finds.
Human-generated noise pollution harms birds globally by disrupting communication, reducing breeding success, and increasing stress, especially in ground-nesting and urban species, according to a large-scale study analyzing data from 160 bird species across six continents.
The research, published in Proceedings of the Royal Society B, finds noise from traffic, construction, and urban development interferes with mating, parenting, and predator avoidance, with urban birds showing higher stress hormones.
Despite being overlooked compared to climate change and habitat loss, noise pollution is a major threat to biodiversity, but solutions like sound-absorbing materials and better urban planning are available and cost-effective.
