How many birds are in the world?

Answer 1

There are approximately 10,000 bird species in the world. This number varies by a few hundred birds, depending on which classification system you use. Clements (now run by Cornell University) lists about 9,800 bird species whereas Sibley and IOU list over 10,000 species.

As with most animal groupings, species are being redefined and what was considered to be one species may be split into two or more species, and in other cases. two species may be combined into one species. Clements is slow to make such changes.

Splits and groupings of bird species happen regularly. It's even more common in butterflies and the taxonomy of moths is an even bigger mess! In the United States (including Hawaii) there are about 980 bird species, depending on the listing source.
