Avian Monitoring: a) Migration Monitoring b) Monitoring Avian Productivity and Survivorship (MAPS)

Project Description

The Koffler Scientific Reserve is one of the larger remaining blocks of GTA natural habitat available to migratory birds en route between wintering and breeding areas. With a focus on species that breed in the boreal forest, the migration monitoring study investigates the use of the KSR reserve by avian species through mark and recapture (bird banding). In addition to determining what species stop at the reserve, measures of individual condition, including fat stores, will provide information on the quality of the KSR stopover habitat. Information gained will be valuable to ongoing management of the reserve according to its conservation mission. Similarly, breeding birds will be studied, to determine the numbers of species and individuals breeding within selected wetland and upland habitat. The method estimates the number of young produced and the number surviving to the end of the fledgling period. Data from KSR also contribute to a continental dataset.

Additional Scientific Information

a) Following standard protocols of the Canadian Migration Monitoring Network, individuals are identified to species and age class, sex, and biometrics recorded. Local recapture data provide information on stopover habitat quality. Data also feed into a national dataset with analysis at the wider scale tracking population change. Data are used to report on the state of Canada’s birds, (http://www.ec.gc.ca/indicateurs-indicators/default.asp?lang=en&n=F2BDAA4C-1) and provide a key objective data resource supporting Species at Risk listing for several species, e.g. Acadian flycatcher, Golden-winged warbler, and Bobolink. The current issue with respect to rapidly declining populations of aerial insectivores (swallows and swifts) was first raised through migration monitoring data. Bird Studies Canada cooperates with banders, Universities and the Federal Government to analyze and report on CMMN data. KSR will provide needed data from an inland site (most stations are coastal/Great Lakes). b) Monitoring Avian Productivity and Survival (MAPS) also follows standard protocols. It contributes to continental database providing information on breeding ranges, breeding success and temporal change. Several hundred stations operate across the U.S. with few in Canada. KSR is ideally situated to assist in completing breeding range coverage for several species. Local analysis also provides information on how well KSR is achieving its conservation goals.
