A team of international researchers used eBird data to model the distribution and habitat needs of imperiled vulture species in Ethiopia. Their goal was to identify areas of conservation priority to protect these important members of nature’s “clean-up crew.”
Many birds migrate at night. The cool and calm evening skies make migrating at night a little smoother for birds, but nighttime lights can make their journey more treacherous.
Every year the eBird Status and Trends project updates the abundance visualizations and range maps with millions of new observations submitted by eBirders to provide the most up-to-date information on the status and trends of bird populations. This year, the team modeled relative abundance for 1,009 species across the globe using data from more than […]
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.
