High-resolution data, visualizations, and tools describing where bird populations occur and how they change through time—powered by eBird data and updated annually, providing you with the best available science.
The Cornell Lab of Ornithology teamed up with multiple non-profit organizations, international shorebird collaboratives, biologists, and agencies to create ShorebirdViz—an interactive tool that combines observations of shorebirds in eBird with state-of-the art statistical models and machine learning to produce relative abundance estimates and estimates of population size across the Western Hemisphere.
