Species Status Codes

AL - Accepted Lumps for species that are deemed to be conspecific and are DELETED

AS - Accepted Splits that we deem valid and ADD to Master List

DEL – Deleted from Master List or from active consideration of Proposed Splits

DIS - Changes or corrections of a species Range

ENG – Changes or corrections of English names

EXT--Extinct Taxon

NEW - a newly described taxon as opposed to a revision of prior taxonomy, splits or lumps

PHY – Change that reflects new information on the phylogenetic relationships of the taxon

PL - Proposed Lumps for species that are likely to be treated as conspecific with another taxon and that may be DELETED

PS - Proposed Splits for splits that are being reviewed

TAX - Change of scientific name, including issues of nomenclature (priority, gender etc) and revisions of genera

Updates

Below are summaries of  recent updates (3.1 to date) to the IOC World Bird List. Versions 1.0 to 2.11 emphasized consistent use of  recommended English names and updated species taxonomy.

Versions 3.1+ expand the content and goals of  the IOC World Bird List.  Additions include subspecies and their ranges as well as the authors of scientific names. We  strive to track in a timely way the latest taxonomic advances in ornithology.  Starting with v3.5 we provide a working log of corrections and edits of the nomenclature authorities.  v4.1 and subsequent updates will include revisions of ordinal and family classifications.

Please click on one of the tabs on the pull down menu above for particular sets of  updates, i.e. Species, Subspecies etc.  All of the updated information and species changes are included in the latest version of the list on this website.

We update the Master List webpages on an ongoing basis.

Previous versions  of the Master List are available in the DOI Archive 3.1+

Version 4.3 ( Jul 31, 2014)

The IOC World Bird List 4.3 contains 10,534 extant species (and 150 extinct species)  classified in 40 Orders,  240 Families (plus 3 Incertae Sedis) and 2276 Genera.  The list also includes 20999 subspecies (including 109 extinct ssp), their ranges and  authors.

Changes include:

SPECIES ADDED:                   7

SPECIES DELETED:               3

ENGLISH NAMES:                   5

TAXONOMY:                          19  including a revised classification of  Icteridae and assignment of 8 species from incertae sedis to 5 new families

SUBSPECIES ADDED            83

SUBSPECIES DELETED        43

Subspecies Updates 4.3 begins to incorporate subspecies revisions published in Volume 1 of the fourth edition of Howard and Moore edited by Dickinson and Remsen (2013) covering the non-passerines. As described in the introduction to the subspecies section, although the original IOC subspecies list was based principally on the third edition of Howard and Moore (2003), we chose to modify that list based on our own evaluation of the literature involving alternate subspecies treatments. We continue to follow that course with these updates. As such, not every addition and deletion to the Howard and Moore 4th Edition subspecies list has been adopted here. Where we have added or deleted species following Howard & Moore, we have tried to provide other primary or secondary references which support that decision. Although not specifically listed on the update pages, it should be understood that Dickinson & Remsen, 2103 is the principal reference source in these cases.

The sheer number of revisions to subspecies between the 3rd and 4th editions of H&M precludes us from doing a complete revision of the non-passerines in this update. We will continue to provide those in subsequent updates of the IOC World Bird List and will evaluate and revise the passerine subspecies in a similar manner with the anticipated publication of Volume 2 of H&M 4.

Your feedback is welcomed as we go through this process.
