Indonesia Birding Tours
The fauna of the vast island country of Indonesia is characterized by high levels of biodiversity and endemism due to its distribution over a vast tropical archipelago. Many sources credit Indonesia as the most species-rich country on earth. Indonesia is divided into two ecological regions; western Indonesia, which is more influenced by Asian fauna, and the east, which is more influenced by Australasian species. The Wallace Line, across which lies the Wallacea transitional region, notionally divides the two regions. There is a diverse range of ecosystems, including vast rainforests, beaches, sand dunes, estuaries, mangroves, coral reefs, seagrass beds, coastal mudflats, tidal flats, algal beds, and small island ecosystems. 1718 avian species are distributed across the entire country, which straddles all three of the Asian, Wallacean, Australasian regions.
