- Colugo: Also known as flying lemurs, these mammals glide through the air using a patagium, a membrane that stretches between their limbs. Philippine eagles target colugos as a major part of their diet.
- Giant flying squirrel: These large squirrels are arboreal, living in trees. They serve as another food source for Philippine eagles.
- Philippine macaque: This type of monkey is native to the Philippines and spends much of its time in the trees, making them vulnerable to predation by Philippine eagles.
- Other mammals: Philippine eagles may also occasionally hunt rats, bats, and other small mammals that inhabit the forests.
It is worth noting that Philippine eagles are apex predators, meaning they are at the top of the food chain and have no natural predators. Their hunting prowess and powerful talons allow them to capture and kill their prey efficiently, making them one of the most formidable birds of prey in the world.
