BIRDS REGION

Sumatra and Papua are the regions with the greatest numbers of bird species-605 and 647 respectively; Celebes and Nusa Tenggara, with 379 and 398, have the smallest. By focusing on one of these regions it is quite possible to come away from a 2- or 3-week birding holiday feeling that you know the birds well. Conversely, if your goal is to see as many species as possible, the advice is to choose an itinerary the includes sites in two or more of these regions.

Birds Regions

Within this broad framework-west, transitional and east-biologists have divided Indonesia into seven biological regions based on distinct groupings of unique bird (and animal) species. So, for instance, Celebes has 96 bird species not shared with other regions, and the Lesser Sunda regions, except for Moluccas, where the provincial boundary-which encompasses the Moluccas and parts of the Lesser Sundas, and Papua-has been used for practical travel reasons.
