The Checklist v2025

Broad-billed Roller Eurystomus glaucurus by Shailesh Pinto; Cornell Lab of Ornithology | Macaulay Library

The AviList team worked for four years to harmonize the global checklist of birds. The final product includes a consensus taxonomy combined with a full set of taxonomic and nomenclatural components, the details of which are explained at Components of the AviList checklist. Over time, additional information is expected to be added.

AviList is free for anyone to use and download in XLSX format. Note that each spreadsheet includes five tabs: AviList v2025; Decision summaries; Recommended citation; How to use; and References.
