There are a number of different world bird lists available. The Clements Checklist of the Birds of the World is an established authority for world listing. The 6th edition was published in 2007 and, following the death of Jim Clements in 2005, is now being maintained by the Cornell Laboratory of Ornithology. Cornell are publishing regular updates to the list and BUBO Listing will endeavour to keep up with these updates. The latest updates incorporated are those from October 2022.

Not surprisingly, the taxonomic treatments of various species or subspecies differ between Clements and other authorities. If you are unclear about how any species you have seen relates to the species listed in Clements, then Contact Us and we will endeavour to help.

Note that English names follow Clements in general and thus are the preferred American names, hence Brant instead of Brent Goose, Common Merganser instead of Goosander, Loon instead of Diver (e.g. Common Loon and not Great Northern Diver), Jaeger instead of Skua (e.g. Parasitic Jaeger and not Arctic Skua).

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

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.
