Human-generated noise significantly impacts animal communication and well-being, forcing species like white-crowned sparrows to alter their songs to be heard. During the COVID-19 pandemic, reduced human activity led to a noticeable decrease in noise pollution, allowing these birds to revert to more complex and quieter vocalizations. This demonstrates that anthropogenic noise is a form of pollution that can be mitigated through strategies like electrification and urban planning, potentially reversing its harmful effects on wildlife.
