Collared Dove (Streptopelia decaocto) by Robert Scanlon. Now there’s a Burmese Collard Dove (Streptopelia xanthocycla) split off from it.
Wow! Since I last updated the World Bird List here on this site, 154 new Species have been added, 4 Orders have been added, 2 Families have been added, and 52 Genera have been added in the last two years.
This is what was last count in 2019:
The IOC World Bird List 9.2 contains 10,758 extant species (and 158 extinct species) classified in 40 Orders, 250 Families and 2,320 Genera. The list also includes 20,034 subspecies, their ranges and authors.

Mountain Imperial-Pigeon (Ducula badia) by Ian. Now there’s a Malabar Imperial Pigeon Ducula cuprea is split from Mountain Imperial Pigeon Ducula badia.
This is the new count:
Version 11.2 (July 15, 2021)
The IOC World Bird List 11.2 contains 10,912 extant species (and 160 extinct species) classified in 44 Orders, 252 Families and 2,372 Genera. The list also includes 19,889 subspecies, their ranges and authors.
Over the next few days, (or weeks) I hope to update our pages to the current list. Because of Covid concerns (no birding), and some health issues, I have neglected to update these. I am curious as to what they have added and deleted in the last few years. Stay tuned!
“For I am the LORD, I change not;” (Malachi 3:6 KJV)
Thankfully, Our Lord does not change!!
I did list some of the changes to the 10.1 version, but didn’t update the site. See:
I just discovered these Name Changes to 10.1 as I was finishing this article up. I just may do the same for 10.2 and 11.1 versions so you can see the changes in smaller batches. Stay tuned some more!
So, expect the links to the list to be changing as this process is on going:
