Avibase is an online

American Ornithological Society Checklist of North American Birds
since 1886). Taxonomic concepts in over 230 different taxonomic sources have been mapped and cross-referenced to Avibase concepts.

The website also offers checklists for more than 20,000 geographic regions of the world, species pages with taxonomic information and synonyms, and tools for observers to maintain their own sightings and obtain reports, such as a map showing countries or eBird hotspots with target species.

History and purpose

Avibase was created and is maintained by Denis Lepage, currently senior director, data science and technology at Birds Canada. The data contained in Avibase has been gathered starting around 1991.[8] The Avibase website was launched in June 2003 and has been hosted by Birds Canada (formerly Bird Studies Canada) since its inception.


Taxonomic concepts. The database is organized primarily around a table of unique taxonomic concepts. A taxonomic concept is a way of grouping similar taxa together in a database in a more flexible way as compared to specific species names.

color morphs
and invalid or dubious forms.

Nomenclature data. Each scientific name is described to include citation data and the name associated with the original description. Approximately 87,000 scientific names have been recorded in Avibase, and various types of synonyms are also available.

Regional species checklists are available for more than 20,000 regions of the world. This includes all countries, territories and dependencies, and most regions defined in the GADM subnational layers such as provinces, states, prefectures, counties, departments, municipalities and districts (GADM levels 1 and 2), as well as over 2,500 islands. Regional checklists are available in several taxonomic formats and can incorporate common names in a variety of languages. Data for regional checklists originates from multiple of sources, such as the eBird EBD dataset and forums such as the Facebook Global Rare Bird Alert.

Common names and synonyms are available in 271 different languages and regional variants, and there are 21 languages that have a coverage greater than 85% of species with a known common name.

MyAvibase, launched in 2013, provides free tools for users to maintain their life lists and generate reports that are focused on finding target species that the observer has not yet seen, or general regional statistics (e.g. total number of species by country).
