The BBL codes involved human decisions (see Rules, below, for an example), and some codes are based on historical names which have since changed. The IPB codes are entirely rule-based. The BBL codes are not updated on a fixed schedule and become out of date as names of birds are changed. The IBP codes are updated annually to reflect naming ...

In this list of birds by common name 11,278 extant and recently extinct (since 1500) bird species are recognised. [1] Species marked with a "†" are extinct. Contents
This article lists living orders and families of birds. In total there are about 10,000 species of birds described worldwide, though one estimate of the real number places it at almost twice that. [1] The order passerines (perching birds) alone accounts for well over 5,000 species.
A significant portion of the audiovisual content available in Birds of the World is collected through citizen science data collection as provided by eBird, [3] but content is also included from the Macaulay Library, as it was gathered in the Internet Bird Collection by Josep del Hoyo, the initial founder of Lynx Edicions, and his colleagues in ...
