The Association of European Rarities Committees (AERC) provides an "official" list of birds of the Western Palearctic. The list was originally published in 2003 and was most recently updated in July 2015. It is no longer actively maintained, so we recommend using the IOC Western Palearctic list.

The geographical limits considered by AERC are as defined by the nine-volume Birds of the Western Palearctic - basically Europe, North Africa and a block of the Middle East roughly south and east to Kuwait, but not including Iran nor anywhere east of the Urals and Caspian Sea. For more precise definitions, see BWP.

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.
