ABSTRACT: The Monitoring Avian Productivity and Survivorship (MAPS) Program is a continent-wide bird banding and data collection effort among public agencies, non-governmental organizations, and individuals to assist the conservation of birds and their habitats through demographic monitoring. We analyzed MAPS data from 1992 through 2006 to provide temporal (annual) and spatial (at the scale of Bird Conservation Regions [BCRs]) estimates or indices for key vital rates, including population change, population density, adult apparent survival, recruitment, productivity, and other demographic parameters for 158 species of landbirds. We presented results, along with pair-wise correlations among vital rates, for all 158 species and provided detailed discussions of results and research and management suggestions for 60 of the species (discussions for the remaining 98 species are currently being drafted) on a newly released website, Vital Rates of North American Landbirds (www.vitalratesofnorthamericanlandbirds.org). The results and accompanying discussions provide inferences about which vital rate(s) appear to be driving population change and could significantly improve strategies for reversing population declines that are occurring in many of these species. Here we provide a summary of the information provided on the website and illustrate how the information is presented and interpreted through one example species, Wood Thrush (Hylocichla mustelina).
