Summary

This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross-validation model selection procedure was used to select the best model for each species. Metadata for the BBS data used to produce these estimates is available from a USGS ftp site (ftp://ftpext.usgs.gov/pub/er/md/laurel/BBS/DataFiles/). Metadata associated with this data product provides information specific to the analysis results.

Purpose

These data files and associated web-based summary programs are designed to provide public access to analysis results from BBS data. Primary results are provided in spreadsheet form, and are described in this metadata, and website elements present the results in alternative summary formats. A statement regarding the elements of the website, and a general discussion of the methods, is available at (http://www.mbr-pwrc.usgs.gov). Analysis of survey data can be controversial, and any user of the information should recognize that alternative approaches exist. These results are based on methods that have been peer reviewed and exist in the published literature. Users also have access to all data collected by the survey, at (http://www.pwrc.usgs.gov/bbs/). Standard disclaimers for use of information are also provided (http://www.mbr-pwrc.usgs.gov/bbs/disclaim.html).
