eBird Status and Trends

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.

Explore all Status and Trends species

Visualizations and data products

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.

Migratory journeys and more revealed

Discover when a species migrates, where they go, and where and when are they most common with these mesmerizing abundance animations. These state-of-the art visualizations highlight annual changes in abundance patterns that improve our understanding of bird biology and migration ecology, and guide conservation actions.

Bird abundance—mapped

State-of-the-art statistical models join forces with eBird data to visualize seasonal abundance to help decision-makers prioritize management and conservation actions, and to help you find more birds to power your birding year-round.

Range maps

Meet the new and improved range map based on analytical results powered by eBird sightings to give you more precise information on species distribution. Discover just how far north or south, or east or west a species is expected to occur.

Get the numbers for your state or region

Get relative abundance or the percentage of an area occupied by a species with the abundance and range tables. The tables include estimates to help decision-makers prioritize management and conservation efforts and gain a better understanding of seasonal use of states or regions. Birders can also use these tables to learn how long a species is present in their state or region.

Download the data products

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.
