eBird Science
eBird transforms the global birding community's passion for birds into a powerful resource for research, conservation, and education.
eBird Status and Trends
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.
Use eBird data and tools
eBird is a powerful resource for a wide range of scientific questions. Learn how to access, analyze, and cite eBird data and tools.
Research and conservation applications
eBird plays an increasingly important role in science and conservation. Applications of eBird data range from research and monitoring to species management, habitat protection, and informing law and policy.
Recent science news
Updated abundance and range maps for 2,068 species
Every year the eBird Status and Trends project updates the maps with millions of new observations submitted by eBirders. This year, the team modeled relative abundance for 868 additional species across the globe using data from 464,542 eBirders—bringing the total number of species with visualizations to 2,068.
New Maps Powered by eBird Spotlight Population Increases and Declines
A new, game-changing conservation tool from the Cornell Lab of Ornithology pinpoints bird abundance changes in unprecedented detail. eBirders help make this groundbreaking tool a reality.
2022 Taxonomy Update—COMPLETE
We have now completed the process of updating records in eBird to the most current taxonomy. This year's update resulted in a net gain of 82 species for a new total of 10,906 species worldwide—discover the complete list of updates and which of your records may have changed.
Featured project
ShorebirdViz
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.
