Between June 1989 and October 1990 casual records of rare birds were made in Sabah and on Sipadan Island, Malaysia, and on Luzon, Negros, Bohol and Mindanao, Philippines, with additional observations on Palawan and Tawitawi, Philippines, in August and September 1991. Key sites for bird conservation profiled here are the Angat watershed, Quezon National Park and Candaba Marsh (all on Luzon), Mt Canlaon (Negros), Rajah Sukituna National Park (Bohol), Mt Katanglad (Mindanao), remaining forest on both Tawitawi and Sipadan, and the Danum Valley in Sabah. Notes are provided on 31 species of bird, 17 already considered threatened, three near-threatened. While one threatened species (Nicobar Pigeon Caloenas nicobarica) should be downlisted, at least six species (Spotted Imperial-pigeon Ducula carola, Blue-winged Racquet-tail Prioniturus verticalis, Blue-naped Parrot Tanygnathus lucionensis, McGregor's Cuckoo-shrike Coracina mcgregori, Falcated Wren-babbler Ptilocichla falcata and Palawan Flycatcher Ficedula platenae) should be elevated to threatened status. Records for other species supplement and reinforce current assessments of threat or indicate new distributional or taxonomic information on non-threatened forms.
