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.
The eBird Science team uses state-of-the-art statistical models and machine learning to build visualizations and tools to help decision makers, scientists, and birders alike to better understand migration, abundance patterns, range boundaries, and much more. The team compiles raw eBird data (the when and where people report birds) and high-resolution satellite imagery from NASA, NOAA, and USGS into cutting-edge statistical models to predict when, where, and in what numbers species occur every week of the year.

eBird Status and Trends data products include estimates of species ranges, abundances, and environmental associations. The abundance data products visualized in the latest version (released in December 2020) will be made available in the future, however, abundance data products (released in December 2019) are still available. Regional range and abundance tables as well as the visualizations for the latest results are available by clicking the link below.Download the data products
The new data-driven maps and animations are made possible through support from the National Science Foundation, Wolf Creek Charitable Foundation, Leon Levy Foundation, NASA, Amazon Web Services, Institute for Computational Sustainability, and The Extreme Science and Engineering Discovery Environment (XSEDE).
