Zoogeography of Oriental and Australasian hornbills The geographical distribution and basic ecological requirements of Oriental-Austral- asian hornbills are well documented (Sanft 1960, Ali & Ripley 1970, Medway & Wells 1973, Kemp 1979). It might be noted that the historical distributions of taxa are used in this review, bearing as they do on the evolutionary history of the taxa, even though it is realised that the ranges of many taxa have been contracted recently through removal of forests. The distributions reveal a number of common patterns, common.
