The MAPS (Monitoring Avian Productivity & Survivorship) Program is a continent-wide collaborative effort among public agencies, non-governmental groups, and individuals to assist the conservation of birds and their habitats through demographic monitoring. Since 1989, more than 1,200 MAPS stations spread across nearly every state and Canadian province have collected more than 2 million bird capture records. MAPS data provide insights into important questions such as:
•What factors drive avian population declines?
•Where are problems most acute, on the breeding or non-breeding grounds?
•What drives differences in trends between particular regions or habitats?
•What is the relationship between population change and weather, climate, or habitat loss?
•What can we do to reverse declines?
Most avian monitoring programs in effect today count or estimate numbers of birds to track changes in population size. Estimates of population trend are useful but limited in their capacity to reveal underlying causes of the trends. Demographic monitoring provides inferences about the life-stages of birds that may be most important in limiting population growth.

MAPS uses a standardized, constant-effort protocol with a system of fine mesh nets to capture birds during the summer nesting season. Stations are run by independent banders; state, federal or U.S. government personnel; or by IBP under contract. MAPS operators band the birds and collect information on their age, sex, body condition, and reproductive status. Captured birds are given a lightweight, numbered aluminum leg band and released unharmed. Subsequent recapture data provide information on survival, reproductive rates, and sometimes, movement patterns.

What have we learned from MAPS to date? - IBP and our collaborators have published more than 100 peer-reviewed papers and hundreds of reports on the vital rates of landbirds, and their relationships to climate, habitat, land management actions and other environmental variables. Some of the most important findings are that:
•Survival of adult and first year birds is often as or more important than productivity in driving population declines. This highlights the importance of wintering grounds and migration routes.
•Conditions on wintering grounds and migration routes affect the survival rates and possibly reproductive success of birds the following summer, a phenomenon known as “carry-over effect.”
•Weather, especially the amount and timing of precipitation, and the interaction of weather and habitat, greatly affect vital rates. Considerations of climate are crucial for conservation efforts.
