Avian Conservation Assessment Database

Click Here to View the Latest Assessment Scores

The Avian Conservation Assessment Database (ACAD) contains assessment data for all North American birds from Canada to Panama. The Global ACAD was updated on December 20, 2023. The Regional ACAD and Handbook will be updated soon – check back for updates. In the meantime, the Global ACAD’s changes are summarized here.

The ACAD contains biological information used and generated by the PIF Species Assessment Process, a peer-reviewedscientific methodology for evaluating information related to the conservation of birds. The assessment scores can be viewed online, or downloaded with additional information.

For complete information on scores, assessment methodology, data sources, and uses of the database, download the updated ACAD Handbook.

The ACAD provides two scales of species assessments: global and regional. ACAD uses Bird Conservation Regions (BCRs) as the geographic scale for regional assessments in the U.S. and Canada, but other regions are used in Mexico and countries are used in Central America.

In this “Report Card” from the 2016 State of North America’s Birds report, ACAD scores were used to assess the concern level for all native bird species in Canada, the U.S., and Mexico.
