Eastern Ecological Science Center (EESC) EESC Breeding Bird Survey(BBS) Comments/FAQ(comments)
This website contains the 1966 - 2015 BBS analysis results. These results have undergone internal review. See our disclaimer for cautions regarding the analysis and its interpretation.
Results presented on this website are based on outputs from a series of statistical analyses of BBS data. To conform to USGS data release protocols, we have reviewed the results, and prepared metadata. The full datasets of trend and annual indices analyses are provided in csv format, and can be downloaded from these links:

The primary objective of the BBS has been the estimation of population change for bird encountered along roadsides. However, the data have many potential uses, and investigators have used the data to address a variety of research and management objectives.
Results are generally presented as clickable lists, where regions or species are selected and the website provides summry results from underlying results of analyses with were previously conducted. This way, we provide results that have been reviewed, as consistent with USGS regulations regarding release of information. On-the-fly interactive programs permit additional analyses that are based upon the same underlying analyeses but permit more flexibility in regions and time periods of summary.
Some users will find the clickable list structure of the Summary and Analysis Website to be "old fashioned." We have retained this overall structure to meet the needs of many users of the data, who often harvest results from these lists and thus appreciate consistency in presentation from year to year.
Help files and metadata are presented with summary data, and are also available in the References and Additional Information link on the web site.
We also provide pictures of some of the bird species covered by the BBS. In this version of the Home Page, we provide more pictures of birds, and we provide songs of common birds.
