The Philippine Eagle is a critically endangered forest giant of the Philippines: about 6 kg in the canonical female, roughly a metre long, with a 2 m wingspan and a massive arched bill. It still-hunts flying lemurs, civets and monkeys from canopy perches, and pairs sometimes attack monkey troops together. Its forest ambush is formidable, but low absolute mass and no armor leave it far below large mammals in power and defense.
Detailed ratings
Research-backed ratings on one 0–100 scale for all 273 animals (updated 2026-09-28). How ratings work
Special abilities
Pairs are reported to hunt monkey troops together, one eagle drawing attention from a nearby perch while the partner strikes from behind. In a matchup this adds a distraction-and-flank pattern that single raptors lack.
The eagle sits motionless near the canopy, then works down through the tree layers by gliding from perch to perch before a sudden talon strike. This keeps the first-contact advantage with the eagle.
Unique traits
On Mindanao the Philippine flying lemur makes up more than half of identified prey in nest studies, a narrow prey specialization unusual among large eagles.
A very deep, strongly curved bill, among the most massive of any eagle, used to tear apart prey the feet have secured.
How it fights
Weapons
- The feet and talons do the killing, and the deep, arched bill tears apart prey once it is secured. Prey records show the practical reach of this weapon system: Philippine flying lemurs (colugos), Asian palm civets, macaques, flying squirrels, fruit bats, rats, hornbills and owls, snakes and monitor lizards. A five-pair Mindanao study (1999–2007) found flying lemurs made up 54.2% of identifiable prey, with at least 14 prey taxa recorded and arboreal mammals the most important prey group. Some summaries put flying lemurs as high as 90% of the diet in parts of Mindanao.
- These prey show a raptor able to kill medium arboreal mammals in the canopy, but on the absolute roster a 6 kg eagle still has modest total force. Its prey-killing power is recorded mostly in Weaponry and Attack, not Raw Power.
Struggles vs
- Low absolute body mass compared with medium and large mammals.
- No armor; hollow-boned avian body vulnerable to crushing or grappling.
- Very dependent on intact forest structure.
- Loses most of its advantage if grounded or forced into close contact with a larger terrestrial animal.

Fun facts
- Although known as the "monkey-eating eagle", its main prey in Mindanao nest studies is the Philippine flying lemur, at 54.2% of identified prey items.
- It is the national bird of the Philippines.
- The Peregrine Fund calls it the largest eagle alive by length and wing surface area.
- Satellite-tracked adults on Mindanao had a median home range of about 68 km².
- Parents share care of a single brood for about 20 months, so pairs breed only about every two years.
- Pairs have been reported hunting monkeys as a team, one bird distracting while the other strikes.

L Philippine Eagle battle analysis
The Philippine Eagle is built for one of the hardest hunting problems in the tropics: finding and seizing gliding and climbing mammals in tall, dense dipterocarp forest. It sits almost motionless near the canopy for long periods, then works down through the layers of the forest from perch to perch. When a flying lemur, civet or macaque is found, the feet make the kill and the massive, deep bill finishes the job.
That toolkit is excellent on its own ground. Reported pair hunting on monkey troops, one eagle drawing attention while the other strikes from behind, adds coordination that most raptors lack. Wide forest home ranges, measured by satellite telemetry at a median of around 68 km², show a predator that covers a lot of ground patiently, not in long chases.
On the absolute roster, though, a 6 kg eagle stays a 6 kg eagle. It cannot match the grappling strength, mass or durability of medium and large mammals, and once grounded or pinned it has little protection. Its best matchups are ones where it chooses the moment and angle of contact in forest; open ground, armor, large body size and heavy grappling reverse the result.
Habitat & range
The Philippine Eagle lives only in the Philippines, on Luzon, Samar, Leyte and Mindanao. It lives mainly in remnant primary dipterocarp forest but also uses second-growth and gallery forest. A 2023 habitat model identified about 2.86 million hectares of suitable forest across its range, with Mindanao holding the largest share of breeding pairs.
Diet & hunting
The eagle is the top avian predator of Philippine forests. On Mindanao the Philippine flying lemur is the main prey, supplemented by palm civets, macaques, flying and tree squirrels, fruit bats, rats, snakes, monitor lizards and birds including hornbills and owls. On Luzon, where flying lemurs are absent, macaques and giant cloud rats are reported as principal prey. As a top predator with large space needs it is treated as an umbrella species for Philippine forest conservation.
Social life
Adults live as monogamous territorial pairs, reportedly mating for life unless a partner dies. Telemetry shows a median home range around 68 km² per adult. Hunting is usually solitary, with reported cooperative hunting by pairs on monkey troops.
Conservation
The species is Critically Endangered. A 2023 population estimate based on habitat modelling and telemetry-measured territory size gives about 392 breeding pairs (about 784 mature individuals), higher than earlier estimates of 340 pairs (2018) and 88–221 pairs (1989). The main threats are deforestation and loss of nesting sites, accidental capture in traps set for wild pigs, and shooting, including retaliatory killing after attacks on domestic animals. The Philippine Eagle Foundation runs captive breeding, rescue, rehabilitation and release work.
