The Monitoring Avian Productivity and Survivorship (MAPS) Program is a cooperative program to generate annual indices of adult population size, post-fledging productivity, and estimates of adult survivorship for landbirds at multiple spatial scales. The program consists of a network of constant effort mist-netting and banding stations spread across North America. We use MAPS data collected from 1989 through 1993 (1995 for one analysis) to investigate methods of data collection and analysis, focusing on the following critical areas: density of nets, starting and ending dates each year, number of days of operation per 10-day period, verification of data, pooling of data for between-year comparisons, comparison of indices of adult population size from mist netting and point counts, and the use and interpretation of mark-recapture analyses. Results provide justification for current recommended MAPS methodology: operation of about ten 12-m, 30-mm-mesh mist nets over an area of about 8 ha, for six morning hours per day, for one day per 10-day period, and for six to ten 10-day periods (depending on latitude), with operations beginning after and ending before most of the migrant individuals have passed through the local area.
