Species accounts Table 4. A list of Philippine parrot species that are considered threatened using IUCN Red List criteria. Also included are four species removed from the Red List. Species are listed in alphabetical order by their scientific name, together with the islands on which they occur, and their threat status. The criteria under which each species qualifies are given in the appropriate species account. *Denotes changes from Birds to Watch 2 (and, therefore, the 1996 IUCN Red List of Threatened Animals), which arise from BirdLife International and the Haribon Foundation’s work on Threatened birds of the Philippines (Collar et al. 1998). BirdLife International maintains the IUCN list of threatened birds. Threat English name Scientific name Distribution category Philippine cockatoo

Philippine cockatoo Cacatua haematuropygia
Contributors: Des Allen, Tom Brooks, Guy Dutson and Frank Lambert. Conservation status: IUCN: Critically Endangered (A1c,d; C1; C2a). CITES: Appendix I. National protection status: Information unavailable. Distribution and status: The Philippine cockatoo formerly occurred on all major and many minor islands (comprising
a total number of 45 areas) of the Philippines, but recent visits to roughly half of these have shown that very reduced and often possibly unviable numbers remain on as few as ten islands, chief among them being Palawan and its satellites, and Tawi Tawi (see below). A six-week survey in August–September 1991 yielded a population estimate for Palawan of 800–3,000 birds, of which Pandanas, Bugsuk and Bancalan probably support 100–300 individuals and Dumaran 150–250 individuals, with Tawi Tawi possibly holding several hundred more

Blue-naped parrot Tanygnathus lucionensis
Conservation status: IUCN: Lower Risk, nt (formerly Endangered: A1b,c; A2b,c; C1; C2a). CITES: Appendix II. National protection status: Information unavailable.
The species account for the blue-naped parrot in the Philippines, is the same as that for Indonesia.
Reason for removal from the list: Determining this species’ status is extremely problematic as it is thought to survive in small pockets of habitat on the smaller islands in its range (Collar et al. 1998). This makes assessment of numbers and inference or prediction of population trends difficult. However, its persistence in small numbers, together with the conclusion that it is still fairly numerous in some areas of Palawan and on Tawi Tawi (Lambert 1993, D. Allen per N. Collar in litt. 1997), and is found in large numbers in a large tract of forest on Talaud (Riley 1997), suggest that it may be best considered Lower Risk, nt (Collar et al. 1998).

Distribution and status: The blue-naped parrot formerly occurred in lowland forest up to 1,000m throughout the Philippines (in the subspecies lucionensis on Luzon and Mindoro, hybridus on Polillo, and salvadorii in the rest of its range, including 45 Philippine islands), the Talaud Islands, Indonesia, and islands off the north and east of Sabah, East Malaysia (Dickinson et al. 1991). The species was considered common on the larger islands in the Sulu Archipelago in 1971 (du Pont and Rabor 1973) and on Salebabu, Talaud, in 1978 (White and Bruce 1986). It was seen occasionally on Talaud in 1996 where suitable habitat exists on Karakelong, suggesting that the island may support an important population (J. Riley per N. Collar in litt. 1997). The species was noted on Ticao in 1993 (Curio 1994) and in 1996 a pair was recorded on both Simunul and Sibutu. It was not uncommon around Tawawakan Agricultural Research Station, Tawi Tawi (considered widespread on Tawi Tawi: Dutson et al. 1996) and may occur on the small offshore island of Buan (D. Allen in litt. 1997). It was considered common wherever remnant forest patches exist (mostly in the mountains) around Mt. Awu and Mt. Sahengbalira on Sangihe in 1996 (F. Lambert in litt. 1997). Riley (in litt. 1997), however, recorded only a single bird, which may have been an escapee, in five months on Sangihe. Searches have failed to find it on Negros and Siquijor (Evans et al. 1993). It was thought rare on Mindoro (Dutson et al. 1992), although subsequently was considered quite common in Siburan Sub-prison of the Sablayan Prison and Penal Colony (Brooks et al. 1995c). It is thought to be rare on Luzon and elsewhere (Collar et al 1994), in every case as a result of habitat loss and heavy trapping. It was seen regularly in small numbers on Palawan in 1991 in small numbers (especially in the southern half), in areas that still held small patches of forest (F. Lambert in litt. 1997). It is found in Bataan, Quezon, Minalungaw, and St Paul Subterranean River National Parks (N. Collar in litt. 1997).
