I just finished updating this site to the new I.O.C. Version 2.9 List of Birds. It seems to be a challenge around here to keep up with them, but this one wasn’t so bad. All the changes have been made and the Indexes are all corrected. I separated the Genera names from Species names. That meant making 26 new pages, but it should make it easier to find them.
The IOC now list 10,448 species of birds in the world with this version. Some names were changed and so were some taxonomic revisions made. That means in simple terms that they added 15 species, deleted 5, changed the English names of 16 and shuffled the taxonomy 34 times. Most of us would would not notice, but if you live where that bird is active, then it would concern you.
Actually, they are to be highly commended. There are numerous ornithologists and birding organizations all around the world who contribute to this lists. The IOC World Bird List can be found at Worldbirdnames.Org.
Some of the main pages here:
