This website provides results of temporal and spatial analyses of capture-mark-recapture and constant-effort capture-rate data on 158 landbird species collected as part of the Monitoring Avian Productivity and Survivorship (MAPS) program between 1992 and 2006. The objectives of these analyses are to provide estimates of, and explore relationships among, the vital rates and demographic parameters of each of these species in order to provide hypotheses regarding the demographic drivers of temporal and spatial variation in their population dynamics, especially as these results may help inform research, management, and conservation efforts for them.
