Summary statistics

The 2014 version of the Status of Birds in Canada website reports on the changes in population status of roughly 450 species of land birds, shorebirds, waterbirds and waterfowl that regularly occur in Canada. It uses the best available information up to 2014 from a wide variety of monitoring programs in order to assess the species’ population status relative to about 1970 (the date when many of the major bird surveys began).

More detailed information is provided in the individual accounts (see "Species Accounts" in the left hand menu). Below are summaries of the population status (Fig. 1), the reliability rating for that status (Fig. 2), the Canadian responsibility scores (Fig. 3), and the migratory or occurrence categories (Fig. 4) for all species. Table 1 lists the population status category, reliability rating, Canadian responsibility score and migratory or occurrence strategy for individual species.
