The Partners in Flight Species Assessment and Population Estimates databases have been updated! These databases now provide the most comprehensive and up-to-date information on North American landbirds, to be used in conservation assessments and plans at the state/provincial, regional, national, and continental scales. To access the new PIF databases and associated user guides and to view news of updates and changes to both databases, please visit: http://rmbo.org/pifdb/.

PIF Species Assessment Database
The PIF Species Assessment Database now includes scores for all 887 native landbirds in Canada, the continental U.S., and Mexico, along with scores for well-established non-native species. Between 2002 and 2006, the Mexican federal agency CONABIO, in cooperation with Rocky Mountain Bird Observatory and Cornell Lab of Ornithology, applied the PIF Assessment Process to the entire Mexican avifauna through a series of regional and national workshops involving over 100 Mexican biologists. Between 2008 and 2010, the PIF International Science Committee updated and merged the two databases for all landbirds, forming the basis for Saving our Shared Birds: the PIF Tri-National Vision for Landbird Conservation (Berlanga et al. 2010).
All scores, data sources, and other information used for Saving our Shared Birds are contained in the PIF Species Assessment Database, maintained by the Rocky Mountain Bird Observatory. Scores can be viewed online and can be downloaded as .csv text files at http://rmbo.org/pifdb/. Changes to the database will be incorporated periodically and made available in updated versions. Any necessary revisions of the Handbook on Species Assessment will be made at the same time. Older versions of the database and associated documentation have been archived and are also available on the website.
PIF Population Estimates Database
This update of the PIF Population Estimates Database corresponds with the updated Partners in Flight Species Assessment Database and Saving our Shared Birds: the Partners in Flight Tri-national Vision for Landbird Conservation (Berlanga et al. 2010). It replaces the previous version, which corresponded with continental population estimates used in the PIF North American Landbird Conservation Plan (Rich et al. 2004) and stepped-down population estimates for each U.S. state in the Association of Fish and Wildlife Agencies Partners in Flight Landbird Reports (Rosenberg 2004). The extensive work required for this update was primarily completed through the dedication of Peter Blancher, with Environment Canada. Thank you Pete!
The updated database incorporates more recent data from the North American Breeding Bird Survey (1998-2007), additional population data sources such as the Ontario Breeding Bird Atlas, new independent estimates, and other modifications. Details related to changes in this update are provided in the Handbook to the Partners in Flight Population Estimates Database, version 2.0. Partners in Flight continues to seek input and relevant data from throughout the bird conservation community to improve these estimates for future updates. Range-wide (global) and regional (BCR) population estimates can be viewed online and can be downloaded as Excel files at http://rmbo.org/pifdb/. Changes to the database will be incorporated periodically into updated versions and any necessary revisions of the Handbook will be made at the same time.
Maintenance of these databases depends on voluntary support from bird conservation partners. The recent update was completed with support from the Bureau of Land Management, U.S. Department of Defense, U.S. Fish and Wildlife Service, and U.S. Forest Service. Thank you partners!
