The sounds of traffic have a dramatic effect on migratory birds, some researchers at Boise State University are saying, according to the Associated Press.

For a recent study, published in Britain's Proceedings of the Royal Society B, Boise State researchers blasted the sounds of urban traffic from 5,900-foot Lucky Peak, which serves as a pitstop for migrating songbirds. 

There, the researchers observed that songbird numbers decreased by about 25 percent—and some birds all but disappeared. 

The research has implications for conservation and has given urban planners and biologists clues for how to balance human and animal traffic. It is believed to be the first study that isolates the effect of the sound of traffic on bird populations.
