News: June 2025
AVILIST IS PUBLISHED
A new consensus World Bird List has been published on 11th June, 2025. It is freely accessible: www.avilist.org. Avilist is the long awaited result of the desire for a single comprehensive, authoritative world list. It was established by the international Working Group on Avian Nomenclature (WGAC) and is aimed to replace multiple world bird lists, mainly the IOC (International Ornithological Congress) list, the Clements/eBird list, and the BirdLife list. As a consequence, the IOC list will have its last update 15.2 next July or August, and other constituting lists will likewise merge into the single list in due course.
The next update 5.1 of AVIONARY, foreseen for next early autumn, will use Avilist as its primary taxonomic reference, as it uses the IOC list up to now.

Nine languages are added to Avionary: Armenian (HY), Corsican (Corsu, 2 variants: Co1, Co2), Occitan (OC), four Sámi Languages: South (Sma), Lule (Smj), Inari (Smn) and Skolt (Sms), and two Karelian languages: North (Krl) and Olonets (Olo), bringing the total to 60 languages.
