The Institute for Bird Populations (IBP) coordinates the Monitoring Avian Productivity and Survivorship (MAPS) Program to assess and monitor the vital rates and population dynamics of North American landbirds. The MAPS Program utilizes a standardized constant-effort mist netting and banding protocol (DeSante et al. 2010) at a continent-wide network of monitoring stations. Each summer dedicated volunteers operate bird-banding stations to collect data on individual "birds-in-the-hand" representing over 200 species. Analyses of MAPS data provide critical information relating to the ecology, conservation, and management of North American landbird populations and the factors responsible for changes in their populations....
