Research finds yellow warblers near busy roads turn aggressive when traffic drowns out their territorial songs, and noise pollution could cause clashes

If the rumble of trucks, honk of car horns and bustle of the roads leaves you irritable, you are not alone – researchers say the sound of traffic can leave birds in a rage, too.

Researchers have found male Galápagos yellow warblers that live near busy roads on the islands behave more aggressively when they hear songs from another male if they occur in the presence of traffic sounds.
