International Waterbird Census

The International Waterbird Census (IWC) is an organized effort to monitor and record the populations of waterbirds—such as ducks, swans, and waders—across various wetlands and coastal areas worldwide. Conducted annually, it helps track changes in bird numbers and health, providing valuable data for conservation and environmental management. By observing trends over time, scientists and policymakers can identify threats to waterbird habitats, assess the effectiveness of conservation efforts, and make informed decisions to protect these vital species and their ecosystems.
