About the banding maps

Last updated July 2015

The Bird Banding Lab banding maps were created in collaboration with USGS Patuxent Wildlife Research Center (PWRC) and USGS Biodiversity Information Serving Our Nation (BISON), a program of Core Science Analytics, Synthesis, and Libraries (CSAS&L).

This visualization and query tool displays 50 years of bird occurrences by date and location in the US. Most banding and encounter records are stored in the BBL database with a coordinate precision of 10-minute block. Choose a state, and the map displays banding records by those blocks. Each state may be queried for counts of banding records for a single species or for all species. The popup you see when hovering your cursor over a block reports the numbers of bandings, up to 50 species when no single species is selected. The legend below the map categorizes the counts; darker colors mean higher numbers of bandings. Please be patient, it may take a moment to calculate.

As of July 2015, the dataset contained a subset of the full BBL database, with 20 million banding records records for a selection of 275 species. It does not include birds that were rehabilitated, transported, or reared in captivity. Waterfowl, and threatened and endangered species locations are generalized to state, and do not appear here, but may be browsed on BISON.

These banding maps will be updated as we release more data to BISON, and will ultimately summarize 50 million records for over 800 bird species. It is a visual representation of effort, and serves to preview banding records available at BBL for years 1960 through 2010.

For more detailed banding (and encounter) records, please refer to the BBL data request page.
