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. The Avibase website was launched in June 2003 and has been hosted by Birds Canada (formerly Bird Studies Canada) since its inception.

Features

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."Controlling the Taxonomic Variable: Taxonomic Concept Resolution for a Southeastern United States Herbarium Portal."
Franz, Nico, Edward Gilbert, Bertram Ludäscher, and Alan Weakley. 2016. Research Ideas and Outcomes 2 (September): e10610. Each concept represents a unique biological circumscription and has been assigned a unique alphanumeric ID called Avibase ID. Avibase IDs allow the tracking of congruent taxonomic concepts among publication sources. There are approximately 58,000 unique taxonomic concepts described in Avibase. These include concepts traditionally recognized as species and

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
