I don't know how many species of birds each country has. I just know China has a number of 1184 or 1244 or 1253 bird species . Then how about other countries?

Charles Harper said:By the way again, Lihu, where did you get the three different numbers (1184, 1244, 1253) for #species in China?
I'd say to qualify as an endemic, the entire population has to breed in the relevant area, and basically all the population has to remain there all year, except that I don't think an occasional departing vagrant would be allowed to 'de-endemic' it.
