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.
