Birdsong: Declining bird populations making Europe and North America quieter

Springtime birdsong may be becoming quieter and less diverse in North America and Europe due to declining bird populations, which is bad for ecological diversity and may also have a negative impact on human health and well-being.

Researchers found a significant decline in the diversity and intensity of birdsongs across both continents over the past 25 years, which means soundscapes in these regions have become quieter and less varied.
