Pithecophaga jefferyi (Philippine Eagle; Monkey-eating Eagle)

Wikipedia Abstract

The Philippine eagle (Pithecophaga jefferyi), also known as the monkey-eating eagle or great Philippine eagle, is an eagle of the family Accipitridae endemic to forests in the Philippines. It has brown and white-coloured plumage, and a shaggy crest, and generally measures 86 to 102 cm (2.82 to 3.35 ft) in length and weighs 4.7 to 8.0 kilograms (10.4 to 17.6 lb). It is considered the largest of the extant eagles in the world in terms of length and wing surface, with the Steller's sea eagle and the harpy eagle being larger in terms of weight and bulk. Among the rarest and most powerful birds in the world, it has been declared the Philippine national bird. It is critically endangered, mainly due to massive loss of habitat due to deforestation in most of its range. Killing a Philippine eagle i

EDGE Analysis

The Philippine Eagle is one of the world’s largest, most powerful birds of prey. It was formerly known as the Monkey-eating Eagle, as reports from natives told that the raptor preyed exclusively on monkeys. This was later found to be incorrect as more recent studies have revealed the species to prey on a variety of animals ranging from rodents and bats to pigs and monitor lizards. Endemic to the Philippines, the eagle’s small, rapidly declining population has been feared close to extinction for the past 40 years.
