North American Breeding Bird Survey: Population trend and annual indices for Canada, data-version 2009

Population trend estimates based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. The trend results are Canadian trends and thus use data from Canadian BBS routes only. Results are updated annually; these estimates use BBS data from 1970 through 2009. Trends are presented for species, provinces, territories, and Bird Conservation Regions (BCR) for which there are sufficient BBS data for statistical analysis.The estimates were generated using a maximum likelihood, annual index analysis, which differs from the analysis currently used to generate trend and annual index estimates.

Trends are presented for species, provinces, territories and Bird Conservation Regions for which there are sufficient BBS data for statistical analysis. Trends and annual indices are also presented for groups of species (e.g., grassland birds).

The BBS is jointly coordinated by Environment Canada and the U.S. Geological Survey (USGS), Patuxent Wildlife Research Center. Any use of these BBS results for Canada should acknowledge the hundreds of skilled volunteers in Canada who have participated in the BBS over the years and those who have served as provincial or territorial coordinators for the BBS.
