Abstract

It is generally agreed that populations of many North American landbird species, especially forest-inhabiting Neotropical migratory species in eastern North America, are declining. Existing population-trend data, however, provide no information on primary demographic parameters (productivity and survivorship) and thus provide no means for determining at what point in the life cycle problems are occurring or to what extent observed population trends are driven by causal factors that affect avian birth rates (e.g., temperate forest fragmentation) or death rates (e.g., tropical deforestation), or both. Data on primary demographic parameters of these species are crucial for the implementation of effective management practices to reverse their population declines. The Monitoring Avian Productivity and Survivorship (MAPS) program, a cooperative effort among public agencies, private organizations, and bird banders in North America, was designed to provide these critical long-term demographic data.
