Birds adjust their songs and territorial behavior to compete with traffic sounds, even in remote island environments.

While actual road rage is primarily a human trait, some birds on the Galápagos Islands are experiencing their own issues with traffic. Galápagos yellow warblers (Setophaga petechia aureola) that are exposed to noisy traffic appear to show heightened levels of aggression.

Recorded bird songs were played to simulate an intruder, both with and without accompanying traffic noise, and the birds’ responses were measured.

It’s making these angry birds choose fight over flight. Humans aren’t the only ones who are prone to road rage. Scientists have found that certain songbirds in the Galapagos behave more aggressively around traffic noise because it drowns out their warning calls,
