. Bulletin of the British Ornithologists' Club. N. J. Collar & Rudyanto 103 Bull. 2003 123A BUSUANGA I5 ALA WAN BALABAC IS Museum data Non-museum data Fig. 4. The range of Palawan Hornbill Anthracoceros marchei. Black circles are localities identified from published sources. Grey circles are localities identified from unpublished museum specimens. whereas Leyte was the subject of a major review by Parkes (1973), Samar has suffered almost complete neglect, with only one paper in the entire twentieth century (Rand & Rabor 1960) devoted even in part to the island's avifauna. Consequently we find that of its 82 localities for threatened species, no fewer than 49 (60%) are derived solely from museum evidence. Without this significant extra body of testimony, Samar would have remained undistinguished and irrelevant to avian and very possibly biodiversity conservation in the Philippines. Moreover, when forest cover is overlaid it transpires that a substantial part of the island is as yet intact; and when logging concessions and protected areas are added, it further emerges that the situation is poised to change rapidly for the worse, and that not a single protected area is in place to mitigate the circumstance (see Fig. 5). When this was disclosed at a priority- setting meeting held after Threatened birds of the Philippines went to press, it precipitated a major initiative, with USAID/Global Environment Facility support,.
