Global trends in bird species survival – Red List Index of bird species survival by biogeographic realm

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Global trends in bird species survival indicator's Red List Index shows trends in aggregate extinction risk over time (i.e., overall improvement or deterioration in threat status) for bird species on the International Union for Conservation of Nature Red List. The index is derived from the proportion of species changing category due to genuine biological status changes from one assessment to the next, and acts as an indicator of the changing status of global biodiversity. A downward trend in the Red List Index indicates that the set of species assessed has moved to a higher level of extinction risk. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.
