The harpy eagle is a large neotropical species of eagle. It is also called the American harpy eagle to distinguish it from the Papuan eagle, which is sometimes known as the New Guinea harpy eagle or Papuan harpy eagle. It is the largest bird of prey throughout its range, and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy layer. Destruction of its natural habitat has caused it to vanish from many parts of its former range, and it is nearly extirpated from much of Central America. It is the only member of the genus Harpia, which, together with Harpyopsis, Macheiramphus and Morphnus, forms the subfamily Harpiinae.
Region
Neotropics (Central and South America)
Typical Environment
Occurs from southern Mexico through Central America and into much of tropical South America, including the Amazon Basin and Atlantic Forest remnants. It prefers extensive, undisturbed lowland rainforest, especially near river systems and in areas with towering emergent trees. It sometimes persists in selectively logged forests and along forest edges if large trees remain. Local extirpations have occurred where continuous canopy has been heavily fragmented.
Altitude Range
0–900 m (occasionally to 1500 m)
Climate Zone
Tropical

The harpy eagle is among the largest and most powerful eagles, capable of lifting prey nearly equal to its own mass. It specializes in hunting arboreal mammals like sloths and monkeys, using short, broad wings and immense talons to maneuver through dense canopy. Pairs build massive nests high in emergent trees and raise a single chick every 2–3 years, making populations slow to recover. Habitat loss and fragmentation are the primary threats across its range.

Along with sloths, monkeys, such as the tufted capuchin (Cebus appella), are one of the main prey of the harpy eagle[40]

Temperament
solitary and territorial
Flight Pattern
short powerful wingbeats with agile canopy maneuvering; occasional soaring
Social Behavior
Typically seen alone or in bonded pairs defending large territories. Monogamous pairs build huge stick nests in emergent trees like kapok or Brazil nut and reuse them for years. Reproductive rate is low, usually one chick every 2–3 years, with prolonged parental care.
Migratory Pattern
Resident
Song Description
Vocalizations are mostly high-pitched, whistled calls, often given near the nest or during pair interactions. Calls can be plaintive, ringing weee or whee-eee notes that carry through the canopy.
