Juveniles are similar to adults except their upperpart feathers have pale fringes.
The Philippine eagle is typically reported as measuring 86–102 cm in total length.The Philippine eagle was known initially as the Philippine monkey-eating eagle because it was believed to feed on monkeys almost exclusively; this has proven to be inaccurate. This may be because the first examined specimen was found to have undigested pieces of a monkey in its stomach.
