Feeding Ecology and Diet

  • Scientists used to believe earlier that the Philippine eagle feeds almost entirely on the Philippine long-tailed macaque (the Philippine monkey) however this turns out to be false.
  • The eagle is an apex predator and it feeds on anything that comes its way. The prey varies significantly from small mammal to a large Philippine deer weighing 14 kg.
  • The eagles living in the Mindanao Island are more apt to find lemurs whereas those living on Luzon Island feeds on flying foxes, monkeys, giant cloud rats Phloeomys pallidus, birds, and monkeys. It also supplements its diet with some lizards and snakes.
  • In some parts of the country, the Philippine eagle relies 90% on the flying lemurs.
  • The eagle’s diet is also composed of flying squirrels, rats, monitor lizards, macaques, tree squirrels, hornbills, Asian palm civets, and fruit bats.
  • It typically waits on a tree branch and focuses on the prey keeping its body motionless.

Reproductive Biology

  • The female attains the maturity after 5 years of age while the males become mature at 7 years. The Philippine eagle mates for life as it does not change the partner except when it dies.
  • The breeding occurs in the month of July.
  • It renovates a nest with green leaves and is 1.5 m (4.9 ft) across. The nests are built at least 30 meters above the ground.
  • The female lays one or two eggs.
  • The eggs are hatched in 58 – 68 days. Both parents take part in rearing the young with mother doing the most part.
  • The average lifespan of the Philippine eagle is 30 – 60 years.
