IOC World List

The World Bird Names project has been undertaken on behalf of the International Ornithological Congress (IOC). Initially presented as a book by Frank Gill & Minturn Wright (2006), the IOC World List is now a regularly updated online project hosted at www.worldbirdnames.org. Please see 

The version of the IOC list currently used within BUBO Listing is v15.1 (updated April 2025). Since we have many more European users than American we do follow popular English names in most cases, i.e. Brent instead of Brant, Skuas rather than Jaegers, and Divers rather than Loons, and grey instead of gray! Notes provided below incorporate the IOC distribution ranges.

NB: Scientific name should also be updated similarly, e.g. Genus specific A/specific B or Genus specific A [group]
NB: Notes only allow up to 255 characters, but there is no enforcement of this. Anything longer will be truncated without warning.
NB: Species name for the old taxon should be updated to differentiate it from the split taxa using '[lumped]', e.g. Species A [lumped].
