![]() On Mindanao relatively uniform distances of 5-10 miles were found in the 1990s between 14 neighboring areas, with an average of 7 miles. The species occurs at altitudes from 0 to 5,400 feet. Philippine eagles live in primary rainforests, especially in mountainous terrain, secondary forests and gallery forests. Whether it used to occur in the entire Philippines or has always been absent in the drier west of the archipelago is unclear. The total size of its range is estimated at about 56,370 square miles. The Philippine eagle is endemic to the Philippines and is found on four islands: eastern Luzon, Samar, Leyte and Mindanao. However, according to molecular genetic studies, the Philippine eagle is not closely related to these three species, but to the subfamily Circaetinae, which includes the snake or serpent eagles of the genera Circaetus, Spilornis, and Terathopius. Until a presidential decree in 1978 officially changing its name, it was previously known - rather inaccurately as well as disrespectfully - as the monkey-eating eagle.ĭue to similarities in size and behavior the Philippine eagle has long been placed together in a subfamily named Harpiinae with several neotropical species, among them the harpy eagle ( Harpia harpyja), the crested eagle ( Morphnus guianensis), both of South America, and the New Guinea harpy eagle ( Harpyopsis novaeguineae). The first specimen of the Philippine Eagle was collected by John Whitehead in 1896 on Samar, who was told by the natives there that it fed exclusively on monkeys alone the first describers of this bird to Western science would be influenced by this description of its eating habit and give it the name Pithecophaga (Greek: πίθηκος, píthēkos: "monkey" and φᾰγεῖν, phagein: "eating"), "eater of monkeys". Begging young birds express a conspicuous and far-reaching series of high and pointed calls. Males are quite vociferous during courtship. The calls are described as strange-sounding whining or as long, soft or high whistles like "whiiiiiiuh", which usually rise in pitch, but occasionally fall off. At what age the juveniles take on the adult plumage is not yet known. The iris is brown and the legs are a lighter, more whitish yellow. The light tinges of the upper plumage are usually wider and more white than in adult birds. The plumage of young birds differ only slightly from that of the adults. It is also blue-gray in color, the only eagle to have this distinction. The beak is deep, laterally-compressed and massive. The head and top of the neck is adorned with a brown-streaked crest, giving the bird a regal appearance when erect, and possibly inspiring the Tagalog name " Haring Ibon" ("bird king"). It is colored a dark, chocolate brown above, with its wing feathers tinged in a pale cream below the eagle is mainly white. Its wingspan is from 6 to 6.5 feet, and it weighs up to 18 pounds. They are also known to hunt pigs and small dogs.The Philippine eagle female is approximately 3.3 feet long from beak to tail tip, with some specimens in museums a few inches longer. These species predominantly feed on monkeys, birds, Luzon, cloud-rats, flying foxes, monitor lizards, snakes, colugo, civets, owls, and hornbills. The lifespan of Philippine eagle ranges from 30 – 60 years.Deforestation is one of the major causes of its extermination. The Philippine eagles range is about 146,000 sq. They are also found in montane forests and lowlands with a height of more than 1,800 m (5,900 feet). ![]() Around 80 – 230 breeding pairs exist in these places. These types of eagles are native to Philippine and are largely found in Mindanao, Luzon, Leyte, Samar, Mount Apo, Madre National Park, and Kitanglad National Park.Philippine Eagle Where Do Philippine Eagles Live The wingspan of Philippine eagles measure 184 – 202 cm (6.02 – 6.63 feet).The average weight of these males is around 4.5 kg (9.9 lb), while the females are 6 kg (13 lb) by weight.Like other raptors, females are 10% greater than males. One of the longest Philippine eagles measured 112 cm (3.67 feet) under captivity. The average length of male is about 95 cm (3.12 feet), while the females are 105 cm (3.44 feet) long.There is no significant difference between the chicks and adults.The plumage is brown and white, with undersides pure white and yellow legs.Philippine eagles weigh around 4.7 – 8 kg (10 – 18 lb).The length of the Philippine is around 86 – 102 cm (2.82 – 3.35 feet).
