CITES Appendix II. It has been recorded recently from numerous protected areas, including Mts Isarog and Makiling National Parks, the Northern Sierra Madre Natural Park and Bataan Natural Park/Subic Bay on Luzon, Mt Canlaon on Negros, and Mt Kitanglad and Mt Apo Natural Parks and Mt Malindang on Mindanao, and Rajah Sikatuna National Park on Bohol and recently on Mount Irid-Angilo-Binuang of the Southern Sierra Madre in Luzon (J. Ibanez in litt. 2007), as well as Tadao Ilocos Norte, Mt Palay Palay and Mt Banahao (D. Allen in litt. 2012). These sites are legally protected through local government decrees, but the efficacy of this legislation is often unclear and is ineffective at Mt Malindang and in the Southern Sierra Madre (D. Allen in litt. 2012). The species is regularly recorded during surveys for Philippine Eagle Pithecophaga jeffreyi in Luzon (J. Ibanez in litt. 2007).
Conservation Actions Proposed
Conduct further surveys in areas from which the species is known (e.g. Mt Los Dos Cuernos on Luzon, Mts Cabalantian/Capoto-an on Samar), which may merit formal protection. Study the species's ecology, particularly home-range size and dispersal ability to help inform a global population estimate and assess the likely impact of habitat fragmentation. Promote more effective enforcement of legislation designed to control hunting and trading. Gazette the proposed Southern Sierra Madre Protected Landscape. Use remote-sensing to assess forest loss in the Philippines and gauge the species's likely rate of decline and degree of fragmentation of its populations. Research hunting and trade by interviewing local people and visiting wildlife markets.
The Philippine Hawk-Eagle (Nisaetus philippensis), earlier treated under Spizaetus, is a species of bird of prey in the Accipitridae family. Many taxonmists consider the Pinsker's Hawk-Eagle, a former subspecies, raised to full species status. It is endemic to the Philippines.
