The Value of Monitoring Demographic Parameters and Associated Habitat: The BBIRD Program

Courtney J. Conway1 and Thomas E. Martin1

ABSTRACT— To simultaneously conserve all species of non-game birds in North America, we need a long-term plan that includes an effective national monitoring program. Effective monitoring programs should provide (1) early warning signals about potential or developing population declines, (2) information on habitat requirements for population maintenance, and (3) information on the potential causes of observed population declines. A program that monitors demographic parameters can potentially meet these 3 criteria. The BBIRD program was established in 1992 as a national avian monitoring program that replicates intensive local studies of avian nesting productivity at sites across North America. After only 4 years, the program has been extremely successful. BBIRD participants have collected data on more than 25,000 nests from 76 BBIRD sites in 28 states, including data on >20 nests for 102 species. Products resulting from BBIRD nesting productivity studies include 24 papers in peer-reviewed journals, 10 technical reports, 5 book chapters, and 11 completed graduate theses/dissertations. The BBIRD program has both a national and local component and serves both a monitoring and research role, and should be instrumental in aiding avian conservation efforts in North America.
