THE STATUS OF BIRDS IN CANADA WEBSITE: THE TRIALS AND TRIBULATIONS OF SYNTHESIZING MULTIPLE, DISPARATE DATA SOURCES
The Status of Birds in Canada website, created and hosted by Environment Canada, provides an assessment of the current population status for the 400+ species that occur in Canada. Available survey results and their reliability were evaluated to determine the best population monitoring program(s) for each species, and results were synthesized to provide the assessment. The Breeding Bird Survey (BBS) is one of the longest-running, multi-species avian surveys in North America. As such, BBS trends and indices were used as the main data source for landbirds and a handful of other species. However, like most surveys, the BBS has limitations. One of the most serious of these is uneven survey coverage, which is particularly evident in Canada where the concentration of BBS routes across the southern half of the country leaves the boreal and artic biomes largely un-surveyed. Whenever possible, BBS data for northern species were synthesized with those from other major avian surveys, such as the Christmas Bird Count, to provide a complete a picture as possible of their status. This synthesis was challenging, because surveys have different levels of precision, types of bias, and degrees of understanding of the underlying limitations. Here, we present how we used the BBS and other surveys to assess the species that occur in Canada, the challenges that underlie this level of synthesis, and how we hope to address some of these challenges.
