The Philippine Eagle (Pithecophaga jefferyi), also known as the Monkey-eating Eagle, is an eagle of the family Accipitridae that is endemic to the rainforests in the Philippines.[2] Affinities uncertain. Recent molecular study suggested that it may be sister to Circaetus.[3] Monotypic.[4]

From Greek πιθηκοφαγος pithēkophagos ape-eating < πιθηκοφαγεω pithēkophageō to eat ape flesh < πιθηκος pithēkos ape; φαγος phagos glutton < φαγειν phagein to eat;[5] Jeffrey Whitehead (d. 1909) English stockbroker, father of explorer John Whitehead.[6]


It has been declared the Philippine national bird.[7] It is critically endangered, mainly due to massive loss of habitat due to deforestation in most of its range. Killing a Philippine Eagle is punishable under Philippine law by twelve years in jail and heavy fines.[8] Attempts are being made to breed the eagle in captivity, but with a rapidly shrinking habitat, its future looks uncertain.[9]

Description[]

This magnificent eagle is one of the rarest and most endangered birds of prey in the world,[2] with an estimated population of 226 birds.[1] One of the largest of the world's birds of prey, they measure 90–100 cm (35–39 in); 4,700–8,000 g (10.4–17.6 lb); with a wingspan of 184–202 cm (72–80 in),[4] sexes alike, but females are larger than males.[10]
This rain forest eagle has the typical shape of a forest-dwelling raptor: their wings are large with broad, rounded tips and the tail is long; this combination provides speed and agility when the bird manoueuvres amongst the branches.[10] It has brown and white-coloured plumage, and a shaggy crest.

Behaviour[]

At times, the eagle is seen soaring over the forest, but it hunts mainly in the trees, moving from branch and pausing to watch for prey.[2][10] It also hunts from a perch in the trees.[2] The species is sedentary (non-migratory).[4][10]

Diet[]

It takes forest animals such as monkeys,[2][10] flying lemurs (colugos),[2][10] and they are large enough to take down birds up to hornbill size[2][10] and small deer,[2] hence its alternate name, the Monkey-eating Eagle.[10] Snatches monkeys from a low-level attacks.[9]

Calls[]

They utter long, drawn-out whistles that seem weak for such a large and powerful bird.[10]

Reproduction[]

The nest is a bulky structure of sticks and twigs, lined and placed in the fork of a large branch in a tree rising above the surrounding rain forest. A single egg is laid, and the species probably nests only every second year.[10]

Distribution/habitat[]

Now restricted to a few patches of rainforest on some of the Philippine islands,[2] such as Mindanao[11] in heavy forest from 500–4,000 ft (150–1,220 m).[11];
