Bird Conservation Regions (BCRs) (http://www.nabci-us.org/bcrs.htm) are “ecologically distinct regions in North America with similar bird communities, habitats and resource-management issues.”  Bird populations do not recognize administrative boundaries; therefore, BCRs are a biologically meaningful spatial scale at which to make inferences about bird population densities and trends.
