Philippine eagle (Pithecophaga jefferyi)

Physical characteristics

This species has a heavy bill, long tail, broad wings and a shaggy crest that can be raised in displays. Plumage is typically brown with paler underparts streaked with brown. It is one of the largest eagles in terms of length and wing surface, and its powerful talons enable it to capture relatively large arboreal prey.

Range, habitat and diet

The Philippine eagle is endemic to several larger Philippine islands, including Luzon, Samar, Leyte and Mindanao, where it inhabits mature lowland and montane rainforests. It hunts primarily in the forest canopy and preys on tree-dwelling animals: primates, colugos (flying lemurs), large birds and small mammals are among its known prey. Its hunting style relies on stealth, strength and the use of high perches.

Life history and behavior

Breeding pairs occupy large territories and invest heavily in a small number of young. Nests are built high in emergent trees and pairs take long intervals between successful breeding attempts. These life-history traits—late maturity, low reproductive rate and long parental care—make populations slow to recover from declines.

Conservation status and threats

The species is listed as critically endangered and is legally protected under national legislation; conservation measures are supported by research and captive-breeding efforts. Major threats include habitat loss from logging and agricultural conversion, hunting and accidental capture, and the fragmentation of remaining forest patches. Rehabilitation, habitat protection and community outreach are central to recovery efforts supported by NGOs and government agencies under existing protection law.

Importance and distinctions

The Philippine eagle is both an ecological apex predator and a cultural symbol. Its conservation has become a focal point for wider forest protection initiatives. Distinctive features—its crest, large bill and tree-hunting habits—separate it from other large raptors and underline its dependence on intact tropical forest, making it an iconic indicator of biodiversity health in the islands.

• Also called: monkey-eating eagle, haribon, banog.
