North American Breeding Bird Survey Dataset - Archival Releases of Datasets Ending With Years 2000 Through 2015

This page provides access to antiquated versions of the North American Breeding Bird Survey (BBS) dataset that are in a much older, legacy format. These have been superseded by more recent releases. Unless visitors have a specific need for these archived data, they should return to the Main BBS Dataset Page (https://www.sciencebase.gov/catalog/item/52b1dfa8e4b0d9b325230cd9) and choose the most recent data release, as that one will include all BBS data released to date. These data were released prior to the October 1, 2016 effective date for the USGS's policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release.
