The IOC World List has now been updated to the latest published version 11.2, from July 2021.

This is a large update, with about 110 new species available, through splits or new discoveries. Lots to add for Indonesian birders, but several of Western Palearctic interest as well, e.g. the splits of Atlas Wheatear ("Seebohm's) Oenanthe seebohmi (which has been recorded wild in Belgium!), Maghreb Wheatear O. halophila, and Basalt Wheatear O. warriae.

Also Green Bee-eater is split into its separate forms African, Arabian, and Asian, and the eastern form of Graceful Prinia is now Delicate Prinia.

Common (or Mew) Gull has had the North American and Eurasian populations split, so birders on both sides of the Atlantic will be paying close attention for any vagrant Common or Short-billed Gulls!

All our regional or country lists based on IOC, such as the IOC Western Palearctic list, have also been updated. There are likely to be some distribution errors with country lists: we have made a "best guess" on some for now, so please do point out any potential errors you find.

We automatically apply updates where we can, and in other cases you will be prompted for any taxonomic changes to address yourself.

If you have any queries about distributions or identification of individuals so that you know what you can count, do post in the forums so that other BUBO Listers can help out.
