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 to 102 centimetres (2.82 to 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 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 is punishable under Philippine law by twelve years in jail and heavy fines.
