What animal eats the harpy eagle?

Harpy eagles are apex predators and, consequently, only suffer predation from other harpy eagles while they are young and in the nest. Even this is rare, as at least one parent stays in the nest to defend the young. Adult harpy eagles have no natural predators.

The harpy eagle is a large eagle that lives in the treetop canopies of the South American rainforest. They prey on animals that live in trees, such as monkeys and sloths. While they are not endangered, they suffer from habitat loss and occasional shooting by farmers who see them as a threat to their livestock.
