eBird Science

eBird data are a powerful resource for a wide range of scientific questions. eBird Status and Trends highlights Cornell Lab analyses of continental bird abundances, range boundaries, habitats, and trends.

eBird transforms a global birding community’s passion for birds into critical data for research, conservation, and education. By building tools that engage the global birding community, eBird gathers unprecedented volumes of information on where and when birds occur in the world. Half a billion bird observations have been contributed so far. eBird collects ‘complete checklist‘ data, providing year-round information on all bird species at high spatial and temporal resolutions. When combined and analyzed appropriately, these data enable next generation species distribution models that provide full life cycle information about birds at relatively fine scales across broad spatial and temporal extents. These model results inform novel conservation actions, from site-specific information about the occurrence and abundance of birds, to looking at patterns of species abundance across continent-spanning flyways.

eBird data contribute to hundreds of conservation decisions and peer-reviewed papers, thousands of student projects, and help inform research worldwide. Applications range from ecological and ornithological research, to conservation application, to advancing research in the fields of socioeconomics, artificial intelligence, and computer science. Thanks to the contributions of eBirders everywhere, this growing database has become an unparalleled information resource on birds.
