US bird populations continue alarming decline, new report finds

The release of the 2025 U.S. State of the Birds report was announced today at the 90th annual North American Wildlife and Natural Resources Conference in Louisville, Kentucky. The report, produced by a coalition of leading science and conservation organizations, reveals continued widespread declines in American bird populations across all mainland and marine habitats, with 229 species requiring urgent conservation action. The report comes five years after the landmark 2019 study that documented the loss of 3 billion birds in North America over 50 years.
