The North American Breeding Bird Survey Mapping products 1966 - 2022

This data product consists of raster digital data of population change and abundance estimates for 520 species of North American birds estimated from North American Breeding Bird Survey , hereafter referenced as BBS, data. Estimates for 520 species of trend (yearly % change) from 1966-2022 and mean abundances for the interval 2018-2022 are spatially smoothed from data collected on BBS routes. Metadata for the BBS (https://www.sciencebase.gov/catalog/item/64ad9c3dd34e70357a292cee) and BBS regional analyses (https://www.sciencebase.gov/catalog/item/650325c9d34ed30c2058be3b) provide general information on the survey and survey analyses; these metadata provide information specific to the mapping analysis results.
