Population size estimates (number of detectable individuals) rounded to the nearest thousand for breeding bird species. Estimates were derived from abundance models based on Atlas point count data (see Analytical Methods). There is a 95% probability that the true population size falls between the lower and upper bounds (95% confidence intervals). Population size was estimated for 103 species with sufficient data. Estimates could not be calculated for rare or uncommon breeding species and for species that tend to be detected less frequently via point count surveys. Population estimates for colonial waterbird species (gulls, terns, skimmers, cormorants and pelicans) as well as Peregrine Falcon and Red-cockaded Woodpecker are reported separately in individual Species Accounts.
