But for this study, the team performed a wider analysis by pooling data published since 1990 across 160 bird species to see if any broader trends could be established. The study, published in the journal Proceedings of the Royal Society B, found clear evidence of a "pervasive" impact of noise pollution on birds worldwide. In some cases, noise pollution interrupted mating displays, caused males to change their courtship songs, or masked messages between chicks and parents. Some 61 percent of the world's bird species have declining populations, the International Union for Conservation of Nature said in October. But many solutions to combat noise pollution already existed, said the study's senior author Neil Carter, from the University of Michigan.
