Description

Archived population trend estimates, based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. These archived estimates use data from Canadian BBS routes only, collected from 1970 through 2011. Trends are presented for species, provinces, territories, Bird Conservation Regions (BCR), as well as the sub-regions that make up the analytical strata (intersections of BCRs and provinces/territories), for which there are sufficient BBS data for statistical analysis. These estimates were produced using a hierarchical Bayesian model, which differs from the maximum likelihood model that was used to generate BBS trend estimates from 2002 through 2009. Further details on the statistical methods used to produce these estimates is available in the downloadable word documents. The BBS is jointly coordinated by Environment Canada, Canadian Wildlife Service 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. The most current estimates of BBS trends and annual indices can be found at: http://ec.gc.ca/ron-bbs/ General information on the BBS in Canada (e.g., the data collection methods, survey coverage, etc.) can be found at: http://ec.gc.ca/reom-mbs/
