Range & population Buceros hydrocorax is endemic to the Philippines where it occurs on 11 islands: Luzon and Marinduque (race hydrocorax), Samar, Leyte, Bohol, Panaon, Biliran, Calico-an and Buad (race semigaleatus), Dinagat, Siargao, Mindanao (plus Balut, Bucas and Talicud) and Basilan (race mindanensis). It is still patchily common, notably in the Sierra Madre of Luzon, but is likely to be declining across much of its range.

Ecology: This species occurs in largely in primary evergreen forests up to 2,100 m. It is also known to occur locally in mature secondary and selectively-logged forests.

Threats This species suffers from substantial hunting pressure and widespread loss of habitat as a result of logging and conversion to agriculture.

Conservation measures underway CITES Appendix II.

Conservation measures proposed Monitor populations across the range to determine the magnitude of declines and rates of range contraction. Campaign for the protection of remaining tracts of lowland forest throughout the range.
