About
AviList is a unified, expert-driven global bird checklist designed to resolve longstanding confusion caused by inconsistent taxonomic sources across the ornithological and conservation communities. Produced through a collaborative international effort, the checklist consolidates taxonomy and nomenclature for over 11,131 bird species across 46 orders, 252 families, and 2,376 genera, along with 19,879 recognized subspecies. The checklist is freely downloadable in multiple open-access formats, making it an essential reference for ornithologists, amateur birders, biologists, conservation practitioners, legislators, and biodiversity data platforms. AviList provides clear rationale for taxonomic decisions in complex or controversial species groups, helping researchers and stakeholders align on a consistent standard. As a living document, AviList is updated annually to reflect the latest scientific evidence. The first version was published in June 2025, with the accompanying peer-reviewed paper in *Biodiversity and Conservation* formally introducing AviList as the global standard for avian taxonomy. AviList is ideal for anyone who needs a reliable, standardized, and regularly maintained reference for bird classification — whether for scientific research, citizen science projects, database integration, legislative use, or conservation planning. Its open governance structure, transparent proposal system, and global committee of experts ensure it remains current, credible, and community-driven.
