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. The Clements checklist from 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. In North America, there are about 2,000 bird species, depending on the listing source. About 1,000 species of birds have been seen in Europe. By far the largest concentration of bird species are found in South America. Over 3,200 species have been seen there. In Colombia, Bolivia and Peru the species count for each country tops 1,700. Africa, Asia and Australasia boast about 2,300 and 2,900 and 1,700 species respectively. Finally, Antarctica has about 65 different species of birds there. In 1758, a Swede named Carolus Linnaeus (Carl von Linne) developed a classification system for all animals. He divided the Animal Kingdom into groups that share things in common. Then he divided those groups into smaller groups that had even more things in common. When he finally finished, there were seven levels in his system. At the lowest level is the species. His scientific classification system is still used today.
