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 544 species of birds in five spreadsheets containing trend estimates for three time periods and annual indices for two 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 associated with this data product provides information specific to the associated analysis results; metadata for the BBS data are available at Ziolkowski, D.J., Lutmerding, M., Skalos, S.M., English, W.B., and Hudson, M-A.R., 2025, North American Breeding Bird Survey Dataset 1966 - 2024: U.S. Geological Survey data release, https://doi.org/10.5066/P14SNUV4.
