The Philippine eagle (Pithecophaga jefferyi) is the world's largest eagle by length and one of the most critically endangered raptors. Endemic to the Philippines, it survives in rapidly shrinking old-growth forests and faces constant threats from habitat loss and shooting.
Philippine eagles in the wild suffer primarily from habitat loss: as forests are cleared for agriculture, their prey base collapses and territory size becomes insufficient for successful breeding. Captive individuals at rehabilitation centres require large enclosures mimicking forest structure, varied prey items, and minimal human habituation to maintain suitability for release. Post-release monitoring shows significant mortality during the adaptation period. Injured birds from shooting require lengthy rehabilitation, and many cannot be released due to permanent wing damage.
