There are approximately 10,000 known species of birds in the world. The best continent for bird watching is South America where over 3,200 species are known to exist. Although various different kinds of birds can be seen throughout the world.
There are about as many as 10,000 bird species in the world. Thats sad. Very sad. :(
My guess is roughly around 10,000
500 hundred birds
I would say about 15,000
There is over 11,000 thousands of bird species
