The great attraction of birding in Indonesia is the large number of species found nowhere else on earth: 381, or 4% of all bird species. Every serious “world lister” must come to Indonesia some time. For the purpose of targeting scarce conservation resources, Birdlife International has identified areas of the globe with concentrations of unique species. They are termed Endemic Bird Areas (EBAs) and Indonesia, with 24, has more EBAs than any other nation.
