Collapsing bird numbers in North America prompt fears of ecological crisis – research

Bird populations in North America are rapidly declining, affecting nearly three-quarters of species analyzed across the continent. This trend is most severe in areas once considered bird strongholds, such as grasslands and drylands, particularly in the Arctic region. Researchers employed eBird data from Princeton University to track changes over a 14-year period with high precision, revealing significant declines that highlight the urgent need for more field research and citizen science initiatives, especially in tropical regions.
