Working Group Avian Checklists (WGAC)

AviList is a global avian checklist created to produce a consensus taxonomy for the birds of the world. It is available online and can be freely downloaded.

Prior to the introduction of AviList in June 2025 there were three widely used and regularly updated global checklists. These separate lists were maintained on behalf of the International Ornithologists' Union, BirdLife International and the Cornell Lab of Ornithology. The lists differed in the number of species recognised and the division of the species into genera and families. At a meeting held in 2018, a group of ornithologists agreed to work together to produce a single consensus taxonomy for the birds of the world. The three former lists have now ceased to make any independent taxonomic updates.
