Welcome to the Partners in Flight (PIF) Databases, managed by Bird Conservancy of the Rockies. Please use the links below to visit the Avian Conservation Assessment Database and Landbird Population Estimates Database. These databases were developed through the voluntary collaboration of dozens of ornithological experts from 10 countries to provide a standardized and transparent system that allows the comparison of conservation status and population estimates at multiple geographic scales for all North American birds.

Database News:

May 2017:The PIF Species Assessment Database, now called the Avian Conservation Assessment Database, has been updated and expanded! The ACAD (for short) includes all regularly-occurring bird species found in North America and adjacent waters from Canada to Panama, including approximately 1600 species of waterbirds, shorebirds, waterfowl and landbirds.

Currently, only the Global ACAD is available while the Regional ACAD undergoes a similar update, expansion and review. For now, the 2012 version of the Regional Species Assessment Database for landbirds remains available, but we caution that this database contains information that has now been updated in the Global ACAD. We expect the Regional ACAD to be completed by the end of 2017, at which time it will be posted on this site.

The expansion of the ACAD to include all avian taxa in continental North America was made possible through the work and collaboration of various groups in addition to PIF, including the U.S. Shorebird Conservation Partnership, the Migratory Bird Joint Ventures, and dozens of ornithologists from across North America who helped populate and review the contents of the database.

We welcome additional feedback from other groups and individuals to improve upon the information in this first version of the ACAD. Please contact us if you find any errors or omissions. We expect to update the Global ACAD within 1-2 years with additional input received.
13 June 2013: New landing page for both databases published. Avian Conservation Assessment Database address changed from pif.rmbo.org and redirected to new landing page.
April/May 2013: Reviewed, edited and incorporated landbird population estimates and related data into the PIF Population Estimates database. New Population Estimates database dissemination website designed and published. Population estimates in Avian Conservation Assessment database harmonized with updated numbers in Population Estimates database.
