IOC World List

The IOC World List has now been replaced by AviList: The Global Avian Checklist. All IOC lists have been migrated to AviList, and IOC is no longer available to use. The latest IOC version was 15.1 (updated April 2025) and this is shown below for information. Since we have many more European users than American we 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.

Originally a book by Frank Gill & Minturn Wright (2006), the World Bird Names project on behalf of the International Ornithological Congress (IOC) was then hosted and updated online at www.worldbirdnames.org. It is no longer maintained and has been replaced by AviList.

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.

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.
NB: Notes only allow up to 255 characters, but there is no enforcement of this. Anything longer will be truncated without warning.
