Welcome to Avibase

Avibase is an extensive database information system about all birds of the world, containing over 4.5 million records about 10,000 species and 22,000 subspecies of birds, including distribution information, taxonomy, synonyms in several languages and more. This site is managed by Denis Lepage and hosted by Bird Studies Canada, the Canadian copartner of Birdlife International. Avibase has been a work in progress since 1992 and I am now pleased to offer it as a service to the bird-watching and scientific community.

2009-06-06: I have updated the checklist of the Faroe Islands.

2009-05-25: ProAves recently published a new version of the Checklist to the birds of Colombia. The Checklist documents 1,871 species of birds found in Colombia as of 2009. Colombia officially remains the most diverse country for birds on the planet, followed by Peru (1,822 species) and Brazil (1,777 species). The document is available for download as a PDF or an Excel file on ProAves web site.

2009-05-23: I just finished integrating version 2.1 of the IOC checklist available at worldbirdnames.org. A list of the revisions introduced in this new version is available here.

2009-05-23: A study of the Phylloscopus warblers in the Sino-Himalayan region published in Vertebrate Zoology in 2008 by Martens, Sun and Päckert (pdf available) is examining the relationships between P. fuscatus, P. fuligiventer, P. affinis, P. armandii and P. subafinis and is proposing 2 new taxon names. The authors have shown that P. fuscatus and P. fuligiventer were sister taxa and are proposing that P. fuscatus weigoldi (from Qinghai) should in fact be considered a subspecies of P. fuligiventer. They also found that the Himalayan (incl. SE Tibet) populations and the Chinese populations (Yunnan, Sichuan, Qinghai, Gansu) of P. affinis are differentiated on the species level. The there recommend splitting the Chinese populations from P. affinis and provided the new name Phylloscopus occisinensis nov. sp. They also found the Himalayan group (P. affinis sensu stricto) itself divided into 2 subspecies: Phylloscopus affinis perflavus nov. ssp. in the west and the nominate form P. affinis affinis in the east.
