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.
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.
The average global population of all mature birds is estimated to be on the order of 100 billion individuals. [1] [2] [3] The total population including younglings is somewhat higher during the breeding season of each species. [3] This list is incomplete, because experts have not estimated all bird numbers.
