We’ve just finished updating the Birdstack database to conform with version 2.2 of the IOC’s world bird list. If your data was affected by any splits or lumps, you will have a notification. For help with the upgrade process, check the taxonomic updates help page and the taxonomic updates screencast.

Highlights include addition of 13 species, 108 English name changes primarily for endemic and near-endemic birds of New Guinea and the Bismarck Archipelago, and resequencing of New World trogons.
