Currently there are believed to be around 9,600 species of birds on earth (the number is growing, as definitions of species change).
About 250 living people have seen 5,000 of them.
About 100 people have seen 6,000.
12 have seen 7,000.
2 have seen 8,000.
About 570 species of birds have been recorded in Belize. I wonder if there is anyone in Belize who has seen them all?
