Philippine eagles inhabit mountainous rainforests on the Philippine islands of Luzon, Samar, Leyte, and Mindanao (the last of which supports most of the birds). Their habitat spans dipterocarp forests—which are composed of large resinous, economically valuable timber trees—and surrounding areas, where they make their nests in the crowns of tall trees.

  How big is the Philippine eagle? The Philippine eagle stands roughly 1 meter (3.3 feet) tall, has a wingspan of about 2 meters (6.6 feet), and can weigh up to 8.2 kg (18 pounds). This brown and white bird of prey is one of the largest eagles in the world in length and wingspan. Its sheer size likely contributed to its becoming the national bird of the Philippines.

  What are the main threats to the Philippine eagle? The main threats include habitat loss due to deforestation, decline in the populations of prey mammals, hunting, trapping, environmental degradation, and bioaccumulation of pesticides. Environmental degradation from mining and pollution also threaten the species. All of these pressures, combined with the bird’s long generation time, have proved to be challenging obstacles to the species’ recovery.

  Philippine eagle, (Pithecophaga jefferyi), large bird of prey inhabiting mountainous rainforests on the Philippine islands of Luzon, Samar, Leyte, and Mindanao (the last of which supports most of the bird’s population). The species is one of the largest eagles in the world in length and wingspan, standing roughly 1 meter (3.3 feet) tall and having an average wingspan of 2 meters (6.6 feet). Some individuals, however, have wingspans that measure up to 2.5 meters (8 feet). It serves as the national bird of the Philippines. It also served as the official mascot for the Southeast Asian Games in 2005 (hosted by the Philippines). The Philippine eagle is a critically endangered species, and population studies have estimated that fewer than 500 mature birds remain in the wild.

  In addition to being imposing in size, the Philippine eagle weighs about 6.5 kg (14.3 pounds). The feathers on the top of the wings and tail are primarily cream-fringed brown and brown, respectively, whereas those on the undersides are mostly white. The species possesses a shaggy crest of long narrow feathers that are a mix of brown and cream. The face is dark gray, the eyes are light blue-gray, and the hooked bill begins as a dark charcoal at the tip that grades into bluish gray. Adult Philippine eagles sport 7.6-cm- (3-inch-) long claws, which help the birds capture and eat prey. Hatchlings are covered in white downy feathers, and feather coloration among juveniles resembles that of adults but with whiter tones mixed with brown on the wings and back.

  Philippine eagles are active during daylight hours. Pairs of the birds patrol territories of up to 133 square km (about 51 square miles) that are composed primarily of mountainous dipterocarp forests, which are made up of large resinous, economically valuable timber trees (see also Dipterocarpaceae). The birds seek out arboreal mammals (such as monkeys, lemurs, civets, and flying squirrels), bats, rodents, snakes, and other birds. The species is an apex predator, having no known predators other than human beings, who sometimes shoot the eagles for food or trap them for zoos and the pet trade.

  Philippine eagles are monogamous, and most breeding adults form pair bonds for life. They nest in the crowns of tall trees and breed from September to December. After mating and fertilization, a female will deposit one to two eggs in a nest. Eggs are incubated by both parents, though the female provides the bulk of the effort. After about 60 days the eggs hatch, and both parents provide food for their young for their first seven to eight weeks of life, until the young fledge. Fledglings will remain with their parents until five to six months of age. Both sexes become sexually mature by age 7, though females may become sexually mature as early as age 4. Individuals are long-lived, being capable of surviving up to 60 years in the wild.

  The International Union for Conservation of Nature and Natural Resources (IUCN) has listed the Philippine eagle as a critically endangered species since 1994. An assessment conducted in 2018 reported that the adult population is estimated to number 180–500 birds. Habitat loss due to deforestation since the 1980s and declining populations of the mammals it preys upon are considered to be the primary threats to this species. Hunting and trapping are a substantial cause of mortality for naive juvenile birds. Environmental degradation from mining and pollution also threaten the species. In addition, wildlife officials suspect that the buildup of pesticides in the birds’ tissues through bioaccumulation may be slowing their reproductive rate. These factors, along with the birds’ long generation time (that is, the time between hatching and sexual maturity) have proved to be challenging obstacles to their population recovery.

  Since Philippine eagle conservation efforts began in 1970, government officials have enacted a series of measures intended to prohibit the direct persecution of the birds and to protect their nests. Moreover, the measures regulate the use of the species’ critical habitat, and several nongovernmental foundations have developed captive breeding programs. The species is often a focus used by educators and conservationists alike as a catalyst for outreach on a variety of biodiversity issues. However, despite such measures, there is no systematic monitoring scheme or action recovery plan for the species.
