A study on habitat and food preference of Philemon buceroides in Moyo island, West Nusa Tenggara was conducted in April 1999 until July 1999. The aim of study is to explore the diversity and composition of plants and foods prefered by P. buceroides in its nature habitat. The results from this study will be very valuable in providing information and managing its conservation in both nature and or in man made habitat (in-situ and ex-situ).
