Galápagos Yellow Warblers Alter Behavior Due to Traffic Noise, Study Finds

New research reveals increased aggression and song adaptations in response to noise pollution, even in remote ecosystems.

The study, published in Animal Behaviour, highlights how traffic noise heightens aggression in Galápagos yellow warblers living near roads.
Researchers found that birds near roads adapt their songs by increasing minimum frequencies to overcome noise interference.
Experiments conducted at 38 sites on Santa Cruz and Floreana Islands revealed behavioral differences based on proximity to roads.
Even minimal traffic, such as on Floreana Island with about 10 vehicles, significantly altered bird behavior.
The findings emphasize the importance of addressing noise pollution in conservation strategies for unique species in fragile ecosystems.
