Abstract:

This web site is intended to 1) provide users access to the estimates of landbird populations published in the North American Landbird Conservation Plan (Rich et al. 2004), which were based mainly on Breeding Bird Survey data from the 1990s, 2) allow users to view and download estimates for landbird populations at a variety of geographic scales, and 3) provide transparent access to the methodologies, assumptions, data sources, and species-specific correction factors used by Partners in Flight to create these estimates. On this site we provide estimates for 1) continental, global, and national populations of all North American species; 2) all Bird Conservation Regions (BCRs) in the U.S. and Canada; 3) individual states and provinces; and 4) portions of Bird Conservation Regions within states and provinces.
