Philippine Eagle






           The Philippine Eagle (Pithecophaga jefferyi), also known as the Monkey-eating Eagle, is an eagle of the family Accipitridae  that is endemic to forests in the Philippines. It has brown and white-coloured plumage, and a shaggy crest, and generally measures 86–102 centimetres (2.82–3.35 ft) in length and weighs 4.7 to 8 kilograms (10 to 18 lb). Among the rarest, largest, and most powerful birds in the world, it has been declared the Philippines 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 is punishable under Philippine law by twelve years in jail and heavy fines.
The Philippine Eagle is endemic to thePhilippines and can be found on four major islands: eastern Luzon, Samar, Leyte and mindanao. The largest number of  eagles reside on Mindanao, with between 82 and 233 breeding pairs. Only six pairs are found on Samar, two on Leyte, and a few on Luzon. It can be found in Northern Sierra Madre National Park on Luzon and Mount Apo and Mount Kitanglad National Park on Mindanao.

           This eagle is found in dipterocarp and mid-montane forests, particularly in steep areas. Its elevation ranges from the lowlands to mountains of over 1,800 metres (5,900 ft). It is estimated that only 9,220 square kilometers (2,280,000 acres) of old growth forest remain in the bird's range.] However, its total estimated range is about 146,000 square kilometers (56,000 sq mi).   The Philippine Eagle was known initially as the Philippine Monkey-Eating Eagle because it was believed to feed on monkeys (the only monkey native to the Philippines is the Philippine Long Tailed  macaque) exclusively; this has proven to be inaccurate. 

The primary prey varies from island to island depending on species availability, particularly in Luzon and Mindanao. This is due to the islands being in different faunal regions. For example, Philippine flying lemurs, the preferred prey in Mindanao, are absent in Luzon. Eagle pairs sometimes hunt troops of monkey cooperatively, with one bird perching nearby to distract the primates allowing the other to swoop in unnoticed for the kill.
