Philippine eagle description
The Philippine eagle (Pithecophaga jefferyi) is the world's largest eagle, and one of the most threatened raptors. The male and female Philippine eagle are similar in appearance, possessing a creamy white belly and underwing, whilst the upperparts are a rich chocolate-brown, with a paler edge (4). The long feathers of the head and nape form a distinctive, shaggy crest and are creamy-buff in colour with black streaks (5). Philippine eagle chicks have white down, and juveniles are similar in appearance to adults but have white margins to the feathers on the back and upperwing (6). The Philippine eagle has heavy, yellow legs with large, powerful claws (5), and the large, deep bill is a bluish-grey (6).

Philippine eagle biology
The Philippine eagle can live to between 30 and 60 years of age (2). It feeds mainly on flying lemurs, palm civets and monkeys, hence the alternative common name of 'monkey-eating eagle'. Other prey items include rats, snakes, flying squirrels, birds and bats (6) (7). Individuals hunt from perches and slowly move downhill from perch to perch before soaring back up the hill upon reaching the bottom (6). Philippine eagle pairs have been observed hunting together; one individual acts as a decoy, drawing the attention of a group of monkeys towards it while its partner executes a surprise attack from the rear (6). Pairs build an enormous nest high in the canopy, usually on an epiphytic fern; one egg is produced between October and December, and the chick is dependent on its parents for around a year (6).Top
Philippine eagle range
This species is endemic to the Philippines and found on parts of the larger islands of Luzon, Samar, Leyte and Mindanao (2). The Philippine eagle was once widespread throughout these islands, and although the current population is unknown it is thought to number fewer than 250 mature individuals (5).Top

Philippine eagle threats
Although probably never abundant, the population of the Philippine eagle has undergone a precipitous decline, primarily as the result of habitat destruction (5). Vast tracts of tropical forests in the Philippines have been cleared for commercial development and for shifting cultivation (5). Mining activities and hunting pose further threats to the survival of this majestic bird, and the accumulation of pesticides may be responsible for a reduction in reproductive rate (5).Top
Philippine eagle conservation
The Philippine eagle is protected by law in the Philippines and occurs in a number of protected areas (5); international trade and movement of this species is also restricted and controlled by CITES (the Convention on International Trade in Endangered Species) (1) (3). The Philippine Eagle Conservation Programme (2) is working on educational campaigns, protecting and monitoring nests and a conservation breeding scheme (7); so far, two captive-bred chicks have been produced with the aim of reintroducing them to the wild (6). In addition, chicks and eggs have been taken from areas of habitat at risk in order to establish a viable captive population from which individuals can be reintroduced to the wild (2). Despite these efforts, however, should habitat loss and subsequent human settlement continue at the current rate it seems doubtful that this majestic species will ever recover.Top
