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 v14.1 (updated January 2024). 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.

First select authority to copy existing species from, then type species name, or enter a new species directly.
Species name is defaulted from the previous species row and should of course be overwritten!
Genus is defaulted from the previous species row but may need overwriting; specific needs to be entered in either case.



Check the boxes below to also add species to the appropriate subordinate authorities. select all | clear all
Delete species

NB: Species name for the old taxon should be updated to differentiate it from the split taxa using a '/' or '[group]', e.g. Species A/Species B or Species A [group].
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].
NB: Scientific should also be updated, using '[lumped]' or brackets for the old specific name, e.g. Genus specific [lumped] or Genus [specific] subspecific.
