摘 要：In 2012, the Rocky Mountain Bird Observatory (RMBO), in cooperation with the National Park Service, completed its eighth year of a habitat-based landbird monitoring program in the Northern Colorado Plateau Inventory and Monitoring Network. This program is de- signed to provide rigorous population trend data for most diurnal, regularly occurring breed- ing landbird species throughout parks of the Northern Colorado Plateau Network (NCPN). This population information is useful for land managers and supports the National Park Services goal of long-term monitoring of biological indicators for network parks. The pro- gram is also consistent with goals emphasized by the U.S. North American Bird Conservation Initiative Monitoring Subcommittee (2007).
