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 (BBS) data. Estimates of trend (yearly % change) from 1966-2022 and mean abundances for the interval 2018-2022 are spatially smoothed from data for each species 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.
