There are more than 10,000 regional checklists in Avibase, offered in 9 different taxonomies, including synonyms in dozens of languages. Each checklist can be viewed with photos shared by the birding community, and also printed as PDF checklists for field use.
These checklists are based on the best information available at this time. They are based on a wide variety of sources that I collated over many years, and are constantly revised.
I am pleased to offer these checklists as a service to birdwatchers, but they are subject to some level of inaccuracy. If you find any error, please do not hesitate to .
Bird Checklists of the World is part of Avibase and Bird links to the World, which are designed and maintained by Denis Lepage, and hosted by Bird Studies Canada, which is a co-partner of Birdlife International.
