A new study has discovered that birds in the Galapagos Islands are changing their behavior due to traffic noise, with those frequently exposed to vehicles showing heightened levels of aggression. During trials involving traffic noise, Galapagos yellow warblers (Setophaga petechia aureola) increased the duration of their songs, increased the minimum frequencies of their songs (to reduce overlap with the traffic noise), and birds living close to roads displayed increased physical aggression.

A new study has discovered that birds in the Galápagos Islands are changing their behaviour due to traffic noise, with those frequently exposed to vehicles showing heightened levels of aggression.
Published in the journal Animal Behaviour and led by experts from Anglia Ruskin University (ARU) and the Konrad Lorenz Research Centre at the University of Vienna, the research examined the impact of vehicle noise pollution on Galápagos yellow warblers (Setophaga petechia aureola), a songbird widespread on the archipelago.
