We have changed the update policy for Clements Checklist. Updates will be posted once per year, in October. Therefore the next update can be expected in October 2008. This new schedule was developed in response to requests and recommendations from the user community. Updates are timed to allow our users ample time to review and revise lists on an annual basis, and to begin each new birding year with the most recent Clements Checklist taxonomy.

 Thank you for your patience as we work through these procedures! For background on the rationale for updates, please see the "methods" section.
