Summary
This page provides access to antiquated versions of the North American Breeding Bird Survey (BBS) dataset that had been used in earlier analyses. Unless visitors have a specific need for these archived data, they should return to the Main BBS Dataset Page and choose the most recent data release, as that one will include all BBS data released to date.
Accessing Historic Data
The “Child Items” section below links to the historic data releases. Each archived release had included:
all data that had been included in the previous release, plus
one subsequent year of data, plus
all taxonomic updates, data corrections, and/or other minor adjustments that had occurred in that intervening year
Release Schedule
The BBS collects data during early summer. The remainder of the BBS year is consumed by the survey's intensive data submission, curation, vetting, and packaging processes. Because of this schedule, the archived releases were published one calendar year after their maximum data year (e.g., the 1966-2000 dataset was released in 2001).
The North American Breeding Bird Survey uses standardized, statistically rigorous protocols to deliver scientifically credible measures of the status, trends, and environmental associations of North American birds. Federal, State, and local resource planners throughout the U.S. and Canada make extensive use of BBS information to identify conservation targets and to wildlife make management decisions.
