Denis Lepage of Bird Studies Canada (part of Bird Life International) manages AviBase, which is an, "extensive database information system about all birds of the world, containing over 19 million records about 10,000 species and 22,000 subspecies of birds, including distribution information, taxonomy, synonyms in several languages, and more." Visitors can explore this list by conducting a text search (available via the search tab) and restrict searches by year, language, species, etc. In addition, visitors have the option of setting up a MyAvibase account, which is a tool designed to help one manage their own bird observation data. While these features may especially appeal to ornithology instructors and researchers, AviBase may also appeal to casual bird-watchers. For example, the "Bird of the day" offers a delightful way to learn about birds around the world.
