The Philippine eagle can live to between 30 and 60 years of age (2). It feeds mainly on flying lemurs, palm civets and monkeys, hence the alternative common name of 'monkey-eating eagle'. Other prey items include rats, snakes, flying squirrels, birds and bats (6) (7). Individuals hunt from perches and slowly move downhill from perch to perch before soaring back up the hill upon reaching the bottom (6). Philippine eagle pairs have been observed hunting together; one individual acts as a decoy, drawing the attention of a group of monkeys towards it while its partner executes a surprise attack from the rear (6). Pairs build an enormous nest high in the canopy, usually on an epiphytic fern; one egg is produced between October and December, and the chick is dependent on its parents for around a year (6).
