The State of Canada’s Birds features a species account for every regularly-occurring bird in Canada. Each species account uses population trend data to determine some key metrics about the species. These include a categorization of the species’ national population trend since 1970 (from Large Decrease through Large Increase), an assessment of confidence in that categorization, a national conservation goal for the species, and an assessment of the species’ current status relative to that goal.

These metrics are accompanied by expert analysis, and a variety of supporting information including population estimates, conservation designations, distribution maps, and phenology. Each account also includes interactive trend graphs and distribution maps. The trend graphs and the data that underpin them can be downloaded, and used with appropriate citation.

The State of Canada’s Birds species accounts are the best available source of information on the status and trends of bird species in Canada. They are a logical starting point if you are performing research or conservation work on any of Canada’s birds.
