The Philippine eagle, also known as the monkey-eating eagle or great Philippine eagle, is a critically endangered species of eagle of the family Accipitridae which is endemic to forests in the Philippines. It has brown and white-colored plumage, a shaggy crest, and generally measures 86 to 102 cm in length and weighs 4.04 to 8.0 kg.
Region
Philippines
Typical Environment
Endemic to the main forested islands of Luzon, Samar, Leyte, and Mindanao. It favors extensive tracts of primary and mature secondary lowland to montane rainforest with large emergent trees for nesting. Territories are vast, often spanning tens of square kilometers, and include steep ravines, ridgelines, and river valleys. The species avoids heavily disturbed areas and requires intact canopy for hunting and nesting.

The Philippine eagle, also called the monkey-eating eagle, is the national bird of the Philippines and one of the world’s largest and rarest raptors. It forms lifelong pairs and breeds very slowly, typically raising a single chick every two years. Severe deforestation and hunting have pushed it to the brink, but intensive conservation and captive-breeding programs continue to help the species recover.
