New World Bird List

[Peter Gent]

All, 

Steve Stachowiak alerted me earlier today that a new list of the world's bird species has been released today: see  https://www.avilist.org/about/ 

This is a multi year effort to combine the 4 or 5 previous lists into a single list that everyone can agree on.  This combines the previous lists of the IOC, ebird/Clements and the American Ornithological Society. The total number of species is 11,131. For example, this list splits the Herring Gull into the four species that last year were recognized in the ebird/Clements list but not in the AOS list. 

At this point I have not had enough time to find whether this new list changes the birds that have been seen in Colorado or their common English names, but my initial thought is that it will not. For example, only the American Herring Gull has been documented in CO, and the other 3 splits have not. 

Cheers,  Peter Gent.
