eBird Data Help Clarify Puzzle in Ranges of Mountain Birds
A new study helps reveal why tropical mountain birds occupy such narrow elevation ranges, a mystery that has puzzled scientists for centuries. While many assumed temperature was responsible for these limited distributions, the latest research suggests competition from other species plays a bigger role in shaping bird ranges.

eBird Impacts: European Bee-eaters expand their range northwards
The breeding range of European Bee-eaters has expanded approximately 1000 km (620 mi) northwards, possibly due to warming temperatures across Europe. A team of researchers recently used eBird data to investigate the relationship between European Bee-eaters and climate and also model future range shifts.
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.
